1 INTRODUCTION

1.1 PREFACEBLUESCOPE LYSAGHT proudly presents this new publication on LYSAGHT

BONDEK®. We have simplified the work of engineers with this singlebook which replaces eight previous publications. Further, it tabluatesthe propping, composite slab data and fire design for varioiussituations, all at one view. Additionally, the book includesBONDEK 2003, our easy-to-use interactive computer software, whichenables you to bypass the tables altogether and get quick and moreeconomical solutions with more options.

BONDEK is the centre of a formwork and reinforcement system forconcrete slab construction. It is a profiled steel sheeting widelyaccepted by the building construction industry to be highlyeconomical, versatile and robust. It has been used to great effect onmany major building projects, as well as countless small ones.

This new work now embodies limit state design philosophy, and isbased on our extensive research conducted on bondek, so theinformation is not applicable to other sheeting profiles.

We now consider concrete-frame buildings, and several major newtechnical developments:

• linear elastic analysis of continuous composite slabs;

• saving of up to 30% in negative reinforcement due to moment redistribution;

• partial shear connection strength theory for designing positive-moment regions;

• increased unsupported spans of BONDEK sheeting at theformwork stage (due to the inclusion of negative moment regioncapacities);

• design for reliable control of flexural cracking in support regions;

• New reinforcement grades D500N and D500L; and

• Enhanced fire design

These developments allow you to make significant improvementscompared with the design methods we previously published forslabs using BONDEK.

1.2 SCOPEThis manual and computer software provide engineers with aconvenient aid to design BONDEK composite slabs used in masonrywall, concrete and steel-frame construction. The book also containspractical construction methods.

1.3 DESIGN METHODS FOR BONDEKThere are three ways you can design concrete slabs using BONDEK.

1. The easiest way of designing for bondek is to run our BONDEK

2003 software included with this manual on the inside backcover (see Chapter 9).

2. Use the design tables in this book.

3. Calculate from first principles using the data in Chapters 2, 3 and 4.

Section 1.13 gives a flowchart outlining the process assumed for design.

1.4 GENERAL DESIGN PARAMETERSThe design solutions are provided for the following broad range of design parameters:

• design loads are essentially uniformly-distributed;

• spans are either simply-supported, or are end and interior spans of continuous slabs;

• BONDEK sheeting has three base metal thicknesses (BMT or tbm) of 1.00, 0.75 or 0.6 mm;

• concrete is either normal density or lightweight;

• vertical deflection limits for a composite slab are L/250 total, or L/250 total and L/500 incremental;

• vertical deflection limits for formwork are L/150 or L/240;

• exposure classifications are A1, A2, B1 and B2 (as defined in AS 3600—2001);

• reinforcement may be normal or low ductility grades 400Y,D500N, D500L or 450F;

• ƒ’c = 25, 32 and 40 MPa

• maximum live load is 15 kPa;

• ratio of the longer slab span (Ll) to the shorter slab span (Ls), of any two adjacent spans, does not exceed 1.2;

• fire resistance periods of 60, 90, 120 and 180 minutes; and

• Masonry-wall, steel or concrete-frame construction.

1.5 MATERIALS: SHEETINGBONDEK is roll-formed from hot dipped, zinc-coated, high tensile zincHI-TEN™ steel, in base metal thicknesses (BMT or tbm) of 1.00, 0.75and 0.6 mm.

The steel conforms to AS1397 grade G550 (550 MPa minimum yieldstrength); and

• Z350 and Z450 coatings

In special circumstances bondek may be obtained:

• in other base metal thickness;

• with a non-standard zinc coating mass;

• with a pre-painted finish to the underside.

The mass of BONDEK sheeting is:

• 13.54 kg/m2 for 1.00 BMT

• 10.25 kg/m2 for 0.75 BMT

• 8.12 kg/m2 for 0.6 BMT.

3

1.6 MATERIALS: CONCRETEρc= 2000 kg/m3 (lightweight) and

ρc= 2400 kg/m3 (normal density)

See Table 1.1 for strengths.

1.7 MATERIALS: REINFORCEMENT• For negative, shrinkage and fire reinforcement use D500N, or

400Y, or 450F grades.

• For negative and shrinkage reinforcement use D500N, or D500L,or 400Y, or 450F grades.

Our design tables assume the use of D500N 10 mm maximumdiameter bars for negative reinforcement. If you want to use othergrades, refer to Section 3.10. If you want to use diameters otherthan 10 mm, run BONDEK 2003. The diameter of reinforcing bars mustnot exceed 20 mm.

1.8 DIMENSIONS AND PROPERTIESThe dimensions and properties of BONDEK are presented in Figure 1.1and Table 1.2.

1.9 AVAILABLE LENGTHBONDEK sheets are readily available, custom-cut, in any length from600 mm up to 19,500 mm (length tolerance +0, –10 mm). Ask usabout longer lengths up to a maximum of 25,000 mm.

To maximise speed of installation, use lengths of BONDEK that covermultiple spans.

1.10 CORROSION PROTECTIONZinc-coated BONDEK will provide long and trouble free life withoutadditional corrosion protection for Exposure classifications A1, A2and B1 as defined in AS 3600—2001, Clause 4.3.

Where the exposed underside of BONDEK is subjected to a moresevere corrosive environment use a suitable corrosion protectionsystem.

In any exposed application, you need to treat the edges of BONDEK

to prevent moisture entering between the concrete and the sheeting(Figure 1.2).

2 FORMWORK DESIGN

2.1 GENERALNew design rules have been developed for the design of LYSAGHT

BONDEK acting as structural formwork for the construction ofcomposite and non-composite slabs (where BONDEK is used as lostformwork). The rules for calculating moment capacities are based ontesting performed at BLUESCOPE LYSAGHT Research and Developmentfacility at Chester Hill, AS/NZS 4600:1996, and a finite element stripbuckling analysis.

The data obtained allowed us to include moment capacities innegative regions of the design model. As a consequence, the spanlimits that previously applied to BONDEK have been increased by up to 8%.

Formwork design calculations are covered in this section—geometriclayout considerations are generally covered in Chapter 5(Construction).

2.2 APPLICATIONOur design tables may be used to detail BONDEK acting as structuralformwork, provided the following conditions are satisfied.

1. The support lines extend across the full width of the sheetingand have a minimum bearing of 50 mm at the ends of thesheets, and 100 mm at intermediate supports over which thesheeting is continuous.

2. The sheets continue over each slab span length without anyintermediate splicing or jointing.

3. The ratio of the longer slab span (L1) to the shorter slab span (Ls)of any two adjacent spans does not exceed 1.2, that is L1/Ls ≤1.2.

4. Prop lines are positioned at equal spacings (L´) within a span (L)in the case of propped construction.

5. The slab has a uniform cross section.

6. The supports are effectively rigid such that their verticaldeflection during the construction phase can be ignored in design.

7. BONDEK formwork is not normally cantilevered, though you canseek advice from our information service for special situations.

8. Separate consideration is given to sides of the sheeting whereedges are restrained or where the side of the sheeting is cutlongitudinally.

2.3 DEFLECTION LIMITSAS 3610—1995 Formwork for concrete, defines five classes ofsurface finish (numbered 1 to 5) covering a broad range ofapplications.

We recommend a deflection limit of span/240 for the design ofcomposite slabs in which good general alignment is required, so thatthe soffit has a good visual quality when viewed as a whole. Weconsider span/240 to be suitable for a Class 3 and 4 surface finishand, in many situations, Class 2. Where alignment affects thethickness of applied finishes (for example vermiculite), you mayconsider a smaller limit of span/270 to be more suitable.

We consider span/150 to be a reasonable maximum deflection limitappropriate for profile steel sheeting in situations where visual qualityis not significant (Class 5).

The design rules presented may be used for deflection limits otherthan those stated above however, for deflection greater thanspan/150, you may contact our information service.

2.4 FORMWORK DESIGN LOADSbondek must be designed as formwork for two stages ofconstruction. Stage I—prior to the placement of the concrete, whichincludes the time:

• during handling and erection of the formwork; and

• once the formwork is erected but prior to the placement of theconcrete, (Stage I as defined in AS 3610—1995.)

When a live load due to stacked materials can be adequatelycontrolled on the site at less than 4 kPa, the reduced design live loadmust be clearly indicated on the formwork documentation.

Stage II—during placement of the concrete up until the concrete hasset (until fcm reaches 15 MPa and concrete is able to act flexurally tosupport additional loads such as stacked materials). No loads fromstacked materials are allowed until the concrete has set.

Stage III—as defined in AS 3610—1995 must not be considered inthe rules presented here.

2.4.1 DEAD LOAD OF BONDEK SHEETINGThe dead load of the BONDEK sheeting (Gsh) is:

(AS 3610—1995, Clause 4.4.2.1)

(Gshis in kPa, when tbmis in mm)

2.4.2 DEAD LOAD OF CONCRETEThe dead load of the concrete (Gc) must include an allowance for theweight of reinforcement as well as the effect of ponding, and iscalculated as:

(AS 3610—1995, Clause 4.4.2.2)

The effect of ponding must be taken as 0.7 times the maximumdeflection (∆) of the sheeting when supporting the wet concrete.

G Dc = +( )ρ 0 7. ∆

G tsh bm= 0 13.

2.4.3 UNIFORM VERTICAL LIVE LOADThe uniform vertical live load (Quv), for the appropriate stage of construction, is:

For Stage I construction

For Stage II construction(AS 3610—1995, Clause 4.4.2.3)

2.4.4 CONCENTRATED VERTICAL LIVELOAD

A concentrated vertical live load (Qc) is:

(over an area 1.6 m2 placed at any location)(AS 3610—1995, Clause 4.4.2.3)

Provided the formwork design conforms to this manual, you need notconsider concentrated loads as specified in AS 2327.1—1996,Appendix F2.

2.4.5 VERTICAL LIVE LOAD DUE TO STACKED MATERIALS

A vertical live load (QM) due to stacked materials is:

For Stage I constructionmaximum

(AS 2327.1—1996 does not allow less than 4 kPa for composite beam construction.)

For Stage II construction(AS 3610—1995, Clause 4.4.2.4)

2.4.6 LOAD COMBINATIONS FOR STRENGTH

The design loads for strength are taken from the following loadcombinations:

For Stage I construction

For Stage II construction

(AS 3610—1995, Clause 4.5.4.1)

2.4.7 LOAD COMBINATIONS FOR SERVICEABILITY

2.4.8 DESIGN FOR STRENGTHDesign moments

The design positive bending moment (M*+) must be calculated fromstatics —treating each span as continuous with design negativemoments over supports —and not exceed the values shown inTable 2.1.

Design negative capacities are significantly less than maximumnegative and positive capacities, because negative regions begin to‘soften’ well before the design positive capacity is reached.

Design shear

The design vertical shear force (V*) must be calculated from statics,treating each span as continuous with design negative momentsover supports as shown in Table 2.1. Each load combination forstrength must be considered and the concentrated vertical live load(Qc) must be placed in a position which maximises the verticalreaction.

Design support reaction

The design support reaction (R*u) must be calculated from statics,treating each span as continuous with design negative momentsover supports as shown in Table 2.1. Each load combination forstrength must be considered and the concentrated vertical live load(Qc) must be placed in a position which maximises the verticalreaction.

Strength of positive moment regions

The design positive moment capacity (φMu.sh+) is given in Table 2.1.

The capacity is applicable when the loading is applied to the pans,or the tops of the ribs provided the distribution width on the ribs is aminimum of 50 mm.

Strength of support regions

The design shear capacity (ØVu.sh) for bearing length of 50 mm ormore, is:

2.4.9 DESIGN FOR SERVICEABILITYThe maximum vertical deflection (∆), at completion of the concreteplacement in all spans, is:

Where:

• the values of the coefficient kd are given in Table 2.2; and

• the value of the effective second moment of area Ief is calculated as follows:

Single span sheets

(for the range of )

Multiple span sheets

(for the range of )

To keep the amount of ponded concrete to a manageable level, the maximum vertical deflection (∆) within any span must not exceed (L or L´ )/150.

3 COMPOSITE SLAB DESIGN

3.1 GENERALThis chapter discusses the parameters upon which our design tablesare based. Solutions to your design problems may be obtained bydirect reference to either our BONDEK 2003 software, or our designtables.

The design solutions are based on partial shear connection theory.Data about the shear connection performance of LYSAGHT BONDEK

have been obtained from slip-block tests and full-scale slab tests.

Mechanical and frictional resistance have now been identified as themajor contributors to the bond, and a composite slab no longerdepends on adhesion bond for anchorage. A method of design forvertical shear is also presented.

Major savings are achieved by allowing moment redistribution fromnegative to positive moment regions in continuous composite slabs,and this leads to a significant reduction in the amount of top-facereinforcing. Our design tables assume the use of 500 N-class fire andnegative reinforcement. In our composite slab design tables, slabthickness has been developed for FRL60. The tables for continuousslabs have been developed for end spans and can be used forinterior spans also. Our BONDEK 2003 software often gives moreeconomical designs.

3.2 CRACK CONTROL OPTIONSAn advanced method of crack control for flexure limits the crackwidth to 0.3 mm. Our design tables assume continuous slabs withflexural cracking control. However, if aesthetics (wide cracks oversupports) is not important, it may be economical to design acontinuous slab as a series of one-way slabs—no negativereinforcement is necessary in such case (refer to Worked example 1,Chapter 6).

Slab design calculations are covered in this section—geometric layoutconsiderations are generally covered in Section 5 (Construction).

3.3 APPLICATIONThe rules presented can be used to design BONDEK composite slabsprovided the following conditions are satisfied.

1. The specified concrete strength grade ƒ´c is in the range 25 MPato 40 MPa (as specified in AS 3600—2001). The concrete densityρc may be either lightweight (1800 ≤ ρc ≤ 2100 kg/m3) or normaldensity (2100 ≤ ρc ≤ 2800 kg/m3) (as specified in AS 3600—1994).

2. The concrete manufacture and materials satisfy the requirementsof AS 3600—2001, Section 19.

3. The lines of support extend across the full width of the sheetingand have a minimum bearing of 50 mm at the ends of thesheets, and 100 min at intermediate supports over whichsheeting is continuous.

4. The ratio of the longer slab span ( L1) to the shorter slab span (Ls ) of any two adjacent spans does not exceed 1.2, that is L1/Ls

≤ 1.2.

5. The slab has a uniform cross-section.

6. The design loads for serviceability and strength design must beuniformly-distributed and static in nature.

7. The bending moments at the supports are only caused by theaction of vertical loads applied to the slab.

8. The exposure classification is A1, A2, B1, or B2.

9. The geometry of the steel sheeting profile must conform to thedimensions and tolerances shown on our production drawings.Sheeting with embossments less than the specified lowercharacteristic value must not be used compositely unless thevalue of Hr is revised.

10. Material and construction requirements for conventionalreinforcing steel must be in accordance with AS 3600—2001,Clause 19.2, and the design yield stress, ( ƒsy ), must be takenfrom AS 3600—2001, Table 6.2.1, for the appropriate type andgrade of reinforcement, and manufacturers’ data.

11. Material and construction requirements for concrete must be inaccordance with AS 3600—2001, Clause 19.1.

12. BONDEK must not be spliced, lapped or joined longitudinally inany way.

13. The permanent support lines must extend across the full width of the slab.

14. Similar to the requirement in AS 2327.1, Clause 4.2.3,composite action must be assumed to exist between the steelsheeting and the concrete once the concrete in the slab hasattained a compressive strength of 15 MPa, that is ƒ´cj ≥ 15 MPa.Prior to the development of composite action duringconstruction (Stage 4 defined in AS 2327.1), potential damage tothe shear connection must be avoided; and no loads fromstacked materials are allowed.

15. The first interior span must have the same thickness as the end span.

3.4 DURABILITYThe exposure classification relevant to the design of BONDEK slabs areA1, A2, B1 and B2 as defined in AS 3600—2001, Clause 4.3.

The minimum concrete cover (c) to reinforcing steel, measured fromthe slab top face, must comply with AS 3600—2001, Table 4.10.3.2.These requirements relevant to the design of BONDEK slabs are inTable 3.1.

The minimum overall depth (D) of BONDEK slabs must at least complywith the requirements given in Table 3.2. The values take intoaccount the appropriate exposure classification and concretestrength grade ƒ´c. They have been derived assuming that theminimum distance from the top face of the top bar to the soffit ofthe slab is 70 mm, and that the cover is equal to the appropriateminimum value specified in Table 3.1.

Crack control is important for durability where cracks could providepathways for ingress of corrosive substances such as water, and alsofor aesthetic reasons. The maximum crack width under long-termserviceability loads must not exceed 0.3 mm.

3.5 DESIGN LOADS

3.5.1 STRENGTH LOAD COMBINATIONSFor strength calculations, design loads for both propped and unpropped construction must be based on the following loadcombination.

Or simplified:

Composite slabs are designed assuming one-way action, and thereforereduction of uniformly-distributed live load is not appropriate.

3.5.2 SERVICEABILITY LOAD COMBINATIONSFor serviceability calculations other than deflection, design loads are based on the relevant load combination from Table 3.3. Appropriate values of ψs and ψl given in AS 1170.1 are used, depending on the type of building occupancy.

3.5.3 DEFLECTIONFor deflection calculations, design loads must be based on the relevant load combination from Table 3.4, provided that the live load (Q) is applied after the removal of any temporary props and after the addition of any deflection-sensitive finishes. For other cases, appropriate design loads must be derived from the principles of mechanics.

The multiplier for creep and shrinkage ( kcs ) is determined in accordance with AS 3600—2001, Clause 8.5.3.3. The ratio Asc /Ast , isobtained by dividing the area of conventional reinforcement incompression by the area of all reinforcement in tension, including sheeting and conventional reinforcement, making no allowance for the different design yield stresses of the steels involved.

Where:

(AS 3600—2001, Clause 8.5.3.3)

For this equation:

• Asc /Ast is to be taken at the midspan cross-section for a simply-supported or continuous span and at the support for a cantilever span; and

• BONDEK sheeting must be included in Ast

For deflections in concrete-frame buildings, refer to Section 3.12.

3.5.4 LIGHTWEIGHT CONCRETE LOADOur design tables assume the use of normal density concrete (2100 < ρc ≤ 2800 kg/m3) as specified in AS 3600—2001. They mayalso be conservatively used for lightweight concrete (1800 < ρc ≤2100 kg/m3). Use BONDEK 2003 for more economical solutions.

3.5.5 SUPERIMPOSED DEAD LOADThe maximum superimposed dead load assumed in our designtables is 1 kPa. However bigger loads might be considered in somedesign situations. It is possible to treat additional superimposeddead loads as factored live load:

Qadditional = 2 Gin excess of 1 kPa (see Worked example 3)

Use BONDEK 2003 for more economical solutions.

3.6 LINEAR ELASTIC ANALYSISFor strength and serviceability calculations, the linear elastic analysismethod of AS 3600—2001, Clause 7.6, must be used to determinedesign bending moments and vertical shear forces. In calculatingaction effects in slabs which are continuous over beams, the verticalflexibility of the supporting beams must be small enough to beignored. For strength calculations, redistrib-ution of moments arepermissible up to the limit defined in AS 3600—2001, Clause 7.6.8,with the following exceptions:

• The redistribution limit in each negative moment region is based on the value of ku in that particular negative-momentregion only.

• Redistribution of moments is permitted from negative-momentregions to positive-moment regions but not from positive-moment regions to negative-moment regions.

• No redistribution of moments are permissible where thecontribution of class 450F and D500L reinforcement (lowductility) has been included in the calculation of the designnegative moment capacity.

The ductility requirements of AS 3600—2001, Clause 7.6.8, neednot be applied to the positive-moment regions of BONDEK slabs.

For strength calculations, the inclusion of pattern variations of liveload results in a bending moment envelope in which some regionsare both negative-moment regions and positive-moment regions.These regions must comply with the requirements for both types of region. For serviceability calculations, pattern live loads must be included for short-term live loads but excluded for long-term live loads.

3.7 DESIGN FOR STRENGTH IN NEGATIVE-MOMENT REGIONS

For strength calculations in negative-moment regions use thedetailed procedure in Design of composite slabs for strength(Design booklet DB3.1, BHP, 1998).

3.7.1 MINIMUM BENDING STRENGTHThe minimum bending strength requirement of AS 3600—2001 mustbe satisfied at all potential hinge locations in negative-momentregions—thus, conventional tensile reinforcement must be providedto ensure that:

Where:

• The negative moment region is part of a cantilever; and

• Class 450F or D500L reinforcement is used to provide negative moment capacity.

3.7.2 SHEAR STRENGTHNegative-moment regions must be designed for shear strength, tosatisfy AS 3600—2001, Section 9. The negative-moment regions of acomposite slab can be treated as solid reinforced-concrete sections.

3.7.3 DETAILING OF CONVENTIONAL TENSILE REINFORCEMENT

Conventional tensile reinforcement in negative-moment regionsmust be detailed in accordance with the relevant requirements forone-way slabs in AS 3600—2001, Clause 9.1.3.

Pattern 1

Negative-moment regions must be designed to satisfy therequirements of AS 3600—2001, Section 9. The composite slabnegative-moment regions can be treated as solid reinforced-concrete sections.

Pattern 2

When live loads exceed twice the dead load (red, bold figures in our design tables), at least one third of negative reinforcement mustcontinue over a whole span.

Shrinkage and fire reinforcement, laid on the top, can be assumed tocontribute to that additional one third of negative reinforcement.

3.7.4 BENDING STRENGTHFor the strength design of negative-moment regions, the presenceof the sheeting in the slab is ignored and the slab designed as anequivalent solid reinforced-concrete member. For this purpose, usethe provisions of AS 3600—2001 as they relate to the design of one-way slabs. For a slab which is continuous over any support, buttreated as simply-supported for strength at that support, the designnegative bending moment at the support ( M*– ) must be taken equalto zero.

In calculating the design negative bending moment ( M*– ) anallowance may be made for negative-to-positive momentredistribution up to the limit specified in AS 3600—2001, Clause7.6.8. Thus, the elastic design bending moment before redistribution ( M*–

e ) may be reduced in magnitude to obtain the design negativebending moment after redistribution ( M*– ).

The nominal negative moment capacity ( Muo– ) is calculated based on

the principles of rectangular stress block theory as defined in AS3600—2001, Clause 8.1.2.

For potential hinge locations at which the neutral axis parameter ( ku

– ), as defined in AS 3600—2001, exceeds 0.4, the requirementsof AS 3600—2001, Clause 8.1.3 must be satisfied. In theapplication of this clause, it may be assumed that the minimumcompressive reinforcement requirement is satisfied by the presenceof the steel sheeting in the negative moment region.

When applying AS 3600—2001, Clause 7.6.8, be sure that:

• redistribution is normally only allowed if Class N or Class Y (as opposed to Classes L or F) reinforcement is used over thesupports;

• the elastic bending moment distribution before redistribution isdetermined assuming uncracked cross-sections; and

• the amount of redistribution is measured by the percentage ofthe moment before redistribution.

3.8 DESIGN FOR STRENGTH IN POSITIVE-MOMENT REGIONS

For strength calculations in positive-moment regions use thedetailed procedure in Design of composite slabs for strength(Design booklet DB3.1, BHP, 1998).

3.8.1 MINIMUM BENDING STRENGTHThe minimum bending strength requirement of AS 3600—2001,Clause 8.1.4.1 must be satisfied at all potential hinge locations inpositive-moment regions, that is, . The steel proportionfor rectangular cross-sections deemed to satisfy this requirementunder Clause 8.1.4.1 must not be used. The contribution of boththe sheeting and the conventional reinforcement must be included inthe calculation of Muo

+.

3.8.2 SHEAR STRENGTHPositive-moment regions must be designed for vertical shearstrength, such that at every cross-section located at distance of atleast D from the face of a support, the design positive vertical shearcapacity ( φVuc

+ ), is not less than the design positive vertical shearforce ( V*+ ). The design positive vertical shear capacity ( φVuc

+ ) maybe calculated in accordance with Design of composite slabs forstrength (Design booklet DB3.1, BHP, 1998).

3.8.3 DETAILING OF CONVENTIONAL TENSILE REINFORCEMENT

The termination locations of any conventional tensile reinforcementin positive-moment regions must be determined by extending thereinforcement a distance D + Lsy.t past the point at which it is nolonger required for strength. The requirements of AS 3600—2001,Clause 9.1.3 do not apply.

To allow the concrete to flow into place, the minimum clear distancebetween parallel bars should be restricted to the larger of either 1.5times the maximum nominal size of aggregate (normally themaximum aggregate size is 20 mm), or the diameter of the largestreinforcing bar.

3.8.4 BENDING STRENGTHPositive-moment regions are designed for bending strength suchthat at every cross-section the design positive moment capacity (φMuo

+ ) is not less than the design positive bending moment ( M*+ ).For slabs analysed using linear elastic analysis, the design positivebending moment ( M*+ ) is calculated such that equilibrium ismaintained after accounting for any redistribution of moments. The design positive moment capacity ( φMuo

+ ) within the slab at eachcross-section may then be calculated on the basis of either acomplete or partial shear connection, as appropriate.

In calculating the design positive moment capacity ( φMuo+ ) at any

slab cross-section, the entire cross-sectional area of the sheeting isassumed to be available to act as longitudinal reinforcement, with itseffectiveness at any particular cross-section being dependent on thedegree of shear connection. Conventional longitudinal tensile andcompressive reinforcement may be considered to contribute to thepositive moment capacity at a cross-section, provided due allowanceis made for the required development length for anchorage of thereinforcement in accordance with AS 3600—2001, Section 13.

The design positive moment capacity ( φMuo+ ) may be calculated in

3.9 DESIGN FOR STRENGTH IN MULTIPLE SPANS

Our design tables have been worked out for end spans ofcontinuous slabs. The data in the tables can be used for interiorspans also, assuming uniform thickness for end an interior spans.BONDEK 2003 will give more economical solutions for interior spans,and also offers the opportunity to design interior spans with reducedthickness as compared with end spans.

3.10 DESIGN OF REINFORCEMENT OTHER THAN CLASS D500N

Our design tables have been worked out for 10 mm diameterD500N reinforcement bars for negative reinforcement.

It is possible to replace D500N negative reinforcement with D500L, 400Y or 450F grades, increasing the area of reinforcement by thefactors shown in Table 3.5. The area of reinforcement required is afunction of:

• yield stress;

• moment redistribution (not allowed for 450F and D500L); and

• crack control (small diameter bars are more effective).

BONDEK 2003 will give more economical solutions and allow moredesign flexibility using other diameters and grades.

3.11 DESIGN FOR SERVICEABILITY

3.11.1 VERTICAL DEFLECTIONSDeflection limits must be selected appropriate to the intended useof the slab. These limits must not exceed those listed in AS 3600—2001, Table 2.4.2. In that table the reference to members supportingmasonry partitions is taken to refer to slabs supporting anydeflection-sensitive finishes. (Incremental deflection is the deflectionwhich occurs after the addition or attachment of supporting masonry partitions.)

Immediate deflections are calculated in accordance with thesimplified method. Incremental and total deflections must becalculated as for immediate deflections, using the appropriatecorresponding load combinations from Clause 3.6.3 of this manual.

Contributions of sheeting and conventional reinforcement must beincluded in the calculation of Ief.

As a guide for calculation of Ief you may use:

• Crack control of beams (Design booklet RCB-1.1(1), BHP, 2000);

• Rules for limit-state design to Australian Standards of simply-supported and continuous BONDEK composite slabs in steel-frameor masonry wall buildings (BHPR/SM/R/005, 1996); and

• Rules for design to Australian Standards of BONDEK compositeslabs in concrete-frame buildings (Report No.BHPR/R/1998/066).

3.11.2 CRACK CONTROL FOR SHRINKAGE AND TEMPERATURE EFFECTS

For bondek slabs with an overall depth (D) not exceeding 250 mm,the one layer of transverse reinforcement is required at any heightwithin the cover slab provided the appropriate concrete cover ismaintained.

However, our design tables, and BONDEK 2003, have been developedassuming shrinkage reinforcement is placed at the top forcontinuous slabs, and at the bottom for single spans. For singlespans, longitudinal reinforcement must be located as specified forFire Detail 2 (Chapter 4). This may result in reduced slab thickness, and less negative and fire reinforcement.

Major bars of shrinkage reinforcement mesh must run across BONDEK ribs.

Using D500N as shrinkage reinforcement (say N10 at 200 mm x N10at 200 mm) will always reduce both negative and firereinforcement—for short spans, it may even eliminate it. This is dueto the normal ductility of D500N which can be treated as firereinforcement and negative reinforcement with momentredistribution. You will have to run BONDEK 2003 for this option.

Determine the cross-sectional area of transverse reinforcementrequired to control cracking of the cover slab, due to shrinkage andtemperature effects, by:

• using AS 3600—2001, Clause 9.4.3.4 (Reinforcement in thesecondary direction in restrained slabs); and

• substituting the overall slab depth (D) with the cover slab depth(D – hr ) in the equations for the minimum cross-sectional area oftransverse reinforcement.

Cross-references of OneSteel’s mesh specifications with Grade 450fabrics are shown in Table 3.7.

3.11.3 CRACK CONTROL FOR FLEXUREFor crack control of slabs in flexure, we recommend that you followOneSteel’s specifications: Crack control of slabs, Part 1: AS 3600Design (Design Booklet RCB-2.1(1).

Since maximum steel stress in cracked sections is a function of a bardiameter, the bar diameter in our tables is 10 mm (the minimumpossible for D500N reinforcement).

The crack control for flexure may not always be required, which isoften the case for A1 exposure classification, and when aestheticsare not important. A continuous slab in such conditions may bedesigned as a series of simply-supported slabs without any negativereinforcement, or as a continuous slab with negative reinforcementdesigned without crack control, depending on which option is more economical.

3.11.4 END SLIP CONTROLCheck each span to ensure that no sheeting end-slip occurs underthe loading for short-term serviceability, as follows:

• Under the loading for strength, determine the critical crosssection in the positive-moment region, which is the cross-sectionat which M*/ ( φMuo ) is the greatest. (The critical cross-section iswhere a major crack is assumed to open, thus causing the testblock to slip towards the end.)

• At the critical cross section in the positive-moment region,determine the distance to the nearer end of the sheeting, xend.

• Calculate the limiting force in the sheeting to produce end slipfrom the equation:

Where:

Tslip is expressed in kN and xend in metres.

(Value of 200 is obtained from tests as an ‘average’ value.)

• Under the loading for short-term serviceability, determine themoment at the critical cross section in the positive-momentregion ( Mss ) and calculate the force in the sheeting ( Tss ) fromcracked elastic analysis of the cross-section. For this purpose,the properties of the sheeting may be considered to be acting ina plane 15 mm above the soffit of the slab.

• Ensure that there is no end slip between the sheeting andconcrete under service loads. To do this check that Tss ≤ Tslip and,if necessary, alter the design for strength of the span (forexample: increase Dc and maybe tbm).

T xslip end= 200

3.12 DESIGN FOR CONCRETE-FRAME BUILDINGS

This section covers design of slabs spanning between wide reinforced-concrete beams (band-beams) or prestressed band-beams of concrete-frame buildings.

Other forms of concrete-frame constructions, such as slabs spanningbetween ‘narrow’ reinforced concrete beams, or reinforced concretewalls, may be designed using the rules for steel-frame and masonrywall buildings.

Use Rules for design to Australian Standards of Bondek compositeslabs in concrete-frame buildings (BHP R/R/1998/006).

Our design tables assume the use of steel-frame or masonry wall buildings. However, they may be used for concrete-frame buildings, with the following restrictions:

• The sheeting end must penetrate at least 25 mm into theconcrete cover on the side of a concrete beam formed up withtemporary formwork (Figure 3.3).

• Where BONDEK terminates, bending moments must be zero ornegative for all loading combinations. If the moments arepositive (BONDEK is in tension), additional bottom anchoragereinforcement must be designed (Figure 3.3 and Table 3.8).Bottom fire reinforcement Detail 2 can be treated as anchoragereinforcement. Development lengths must be designedaccording to AS 3600—2001, Section 13.

• Vertical flexibility of the support beams must be small enough to be ignored.

Our tables don’t allow for any beneficial effect on deflections and propping requirements by band-beams. Run BONDEK 2003 for moreeconomical solutions yielding thinner slabs and fewer props.

For the design of concrete-frame buildings, use the following rules in addition to those of steel-frame or masonry wall buildings:

• Calculate the immediate deflections in accordance with thesimplified method as defined in AS 3600—2001, Clause 8.5.3.1, but don’t use the method of averaging Ief over several cross-sections. Determine the values of Ief at an appropriate number of selected cross-sections referring to the shape of the moment-curvature diagram for the member to enable deflections to becalculated by integration of curvatures along the length. Thecurvature at each cross-section is obtained by dividing thebending moment by EcIef.

• Calculate the nominal positive moment capacity ( Muo+ ) at cross-

sections within the band-beam using conventional reinforced-concrete design methods in accordance with AS 3600—2001.

• Shear capacity must be calculated according to Rules for designto Australian Standards of BONDEK composite slabs in concrete-frame buildings (Report No. BHPR/R/1998/066).

4 FIRE DESIGN

4.1 GENERALThis chapter discusses the parameters relating to the exposure ofthe soffit to fire, upon which our design tables are based. Solutionsto your design problems may be obtained by direct reference toeither our design tables, or our BONDEK 2003 software.

The software has enhanced fire design module which allows BONDEK

sheeting to be partially effective during fire for up to 2 hours.Software will give more economical results. Guide tables in thismanual have not been modified for enhanced fire design.

Reduction factors are applied to allow for the effect of temperatureon the slab materials and slab cross-section. Values of thesereduction factors have been derived from extensive analysis ofBONDEK slab cross-sections. These reduction factors account for theadverse effect of elevated temperatures on the mechanicalproperties of concrete and steel, and also include the effect ofthermally induced stresses caused from the temperature gradientacross the section, resulting in differential thermal expansion.

Extensive testing has been conducted to validate the analysis anddetermine the fire-resistance periods for insulation and integrity.

The distribution of temperature through a cross-section of acomposite slab subject to fire, is affected by the geometry of thesheeting profile (Figure 4.1). The features important in the sheetingprofile are: the rib geometry (shape, height and spacing ofintermediate ribs and lapping ribs), and the pan geometry (such asstiffening flutes).

Fire design calculations are covered in this section—geometriclayout considerations are generally covered in Section 5(Construction).

4.2 APPLICATIONOur fire design tables may be used to detail BONDEK composite slabswhen the soffit is exposed to fire provided the following conditionsare satisfied.

1. The composite slab acts as a one-way element spanning in thedirection of the sheeting ribs for both room temperature and fireconditions.

2. The composite slab has been initially designed and detailed forroom temperature conditions in accordance with this manual.

3. The fire design load is essentially uniformly distributed and staticin nature.

4. Transverse reinforcement for the control of cracking due toshrinkage and temperature effects is provided.

5. Adequate detailing of slab jointing, edges, slab holes andcavities (for penetrating, embedded or encased services) toprovide the appropriate fire resistance period. Alternatively thelocal provision of suitable protection (such as fire spray material)will be necessary.

6. The fire cases are for periods of 60, 90, 120 or 180 minutes.

7. Reinforcement conforms to Section 4.6 of this manual.

4.3 FIRE RESISTANCE PERIODSFour fire cases are considered. In each fire case the fire resistanceperiods for structural adequacy, integrity and insulation are taken tobe of equal duration. The fire cases considered are:

• Fire case F60 = FRL 60/60/60

• Fire case F90 = FRL 90/90/90

• Fire case F120 = FRL 120/120/120

• Fire case F180 = FRL 180/180/180

4.5.2 POTENTIALLY CRITICAL CROSS-SECTIONS

All potentially critical cross sections at which hinges may form mustbe identified (Figure 4.2) and checked for strength. All negativemoment hinges may be assumed to be plastic under fire conditions.

These cross sections correspond to where:

• negative moments are a maximum over supports;

• negative tensile reinforcement is curtailed;

• positive bending moment is a maximum; or

• at any changes in cross section (for example changes in depth orwhere there is a significant hole through the slab).

4.5.3 STRENGTH OF POSITIVE MOMENT REGIONS

At the potentially critical cross section where the positive moment is a maximum, the design strength in bending ( φMuoT

+ ) isdetermined for the given period of fire exposure as follows:

Where:

The reduction factor Rst is given in Table 4.2.

The form of this equation is identical with that used to calculate thedesign strength in bending of under-reinforced concrete cross-sections at room temperature conditions, but makes allowance forthe influence of temperature on the strength of the reinforcing steel.

Similar procedure shall be used to calculate additional capacity due to BONDEK being particularly effective against fire. Reinforcementused to control shrinkage and temperature effects often providesadequate fire resistance.

It is normal to ignore the small design strength in positive bendingassociated with any continuous top face reinforcement, however onsome projects this may be sufficient to provide an equilibrium statewithout the need to provide any additional reinforcement.

At the end of the fire period the value of kuT+ where the positive

moment is a maximum:

Where:

The reduction factor ( Rst ) is given in Table 4.2; and γ = [0.85 - 0.007(f´c – 28)] within the limits of 0.65 to 0.85, and f´c must be in MPa (AS 3600—2001, Clause 8.1.2.2).

4.5.4 STRENGTH OF NEGATIVE MOMENT REGIONS

At the potentially critical cross sections associated with negativemoments over supports, or where the negative steel is curtailed, thedesign strength in bending ( φMuoT

+ ) for the given period of fireexposure is:

Where:

The reduction factor Rst is given in Table 4.2; and dx is given inTable 4.3.

This equation takes into account the adverse effect of elevatedtemperatures on the compressive strength of the concrete in theslab soffit, and also includes the effect of thermally induced stresses.

4.5.5 CHECK FOR STRUCTURAL ADEQUACY

The structural adequacy of the end, interior or simple spans must bechecked for the assumed period of fire exposure. Do this by findingan equilibrium state whereby—under the applied loads ( ωf ) — thebending moments ( Mz ) at the potentially critical cross sections, donot exceed the relevant values of positive and negative designbending strength φMuoT

+ and φMuoT– respectively.

Interior spans (Figure 4.2)

The bending moment distribution along an interior span for anassumed pair of plastic hinges at potentially critical cross sections innegative bending can be expressed as:

The minimum bending moment (Mmin) corresponds to the maximumpositive value and is located between the ends of the member. Thelocation of Mmin can be found from:

4.6 REINFORCEMENT FOR FIRE DESIGNThe arrangement of reinforcement for fire design is shown inFigure 4.5.

Fire reinforcement is essential, in addition to any negativereinforcement required by our tables for composite slab design.

The temperature and shrinkage reinforcement of grades D500N,400Y or 450F can be treated as fire reinforcement if located anddetailed in accordance with Figure 4.5—it may significantly reducefire reinforcement, or even eliminate it.

The location of reinforcement Ast.f– for Fire detail 1 is in a single

top layer at a depth of dct below the slab top face (Figure 4.5). This detail is applicable to end and interior spans only.

The location of reinforcement Ast.f+ for Fire detail 2 is in a single

bottom layer at a distance of yb above the slab soffit (Figure 4.5).This detail is applicable to end spans, interior spans and simplespans. The fire reinforcement Ast.f

+ must be continuous over interior supports.

The cross-sectional area of the additional reinforcement for firedesign is designated Ast.f in our tables (D500N with φ≥ 10 mm).

The negative reinforcement ( Ast– ) and the additional fire

reinforcement ( Ast.f+ or Ast.f- as applicable), must be located a

distance xb minimum from the centre of any rib.

D500N, 450F or 400Y reinforcement can be used for fire design.D500L reinforcement is not allowed as negative reinforcement in firedesigns. The limitation is due to hinge formation requirements,which may not be satisfied with only 1.5% uniform elongation forD500L. Further research may be needed to determine the suitabilityof D500L reinforcement for fire design.

D500N fire reinforcement may be replaced with 400Y or 450Fgrades, increasing the area of reinforcement by the factors shown inTable 4.4.

The longitudinal bars which make up Ast.f+ are located within the

zone shown in Figure 4.6. The proximity of the bars to the sheetingribs, or the slab soffit, affects their temperature and therefore theirstrength under fire conditions.

5 CONSTRUCTION

The construction of LYSAGHT BONDEK composite slabs follows simple,familiar and widely-accepted building practice. Workers can readilyacquire the skills necessary to install BONDEK formwork and finish thecomposite slab. Construction workers will normally be supplied withfully detailed drawings showing the direction of the ribs, otherreinforcement and all supporting details.

5.1 SAFETYBONDEK is available in long lengths, so large areas can be quickly and easily covered to form a safe working platform duringconstruction. One level of formwork gives immediate protectionfrom the weather, and safety to people working on the floor below.The minimal propping requirements provide a relatively open area to the floor below.

The bold embossments along the top of the ribs of BONDEK enhancesafety by reducing the likelihood of workers slipping. Some LYSAGHT

centres, may supply BONDEK with knurling on the upper face of theflutes, which provides even more safety against slippage.

It is commonsense to work safely, protecting yourself and workmatesfrom accidents on the site. Safety includes the practices you use; as well as personal protection of eyes and skin from sunburn, and hearing from noise. For personal safety, and to protect thesurface finish of BONDEK, wear clean dry gloves. Don’t slide sheetsover rough surfaces or over each other. Always carry tools, don’tdrag them.

Occupational health and safety laws enforce safe working conditionsin most locations. Laws in every state require you to have fallprotection which includes safety mesh, personal harnesses andperimeter guardrails where they are appropriate. We recommendthat you adhere strictly to all laws that apply to your site.

BONDEK is capable of withstanding temporary construction loadsincluding the mass of workmen, equipment and materials all inaccordance with AS 3610—1995. However, it is good constructionpractice to ensure protection from concentrated loads, such asbarrows, by use of some means such as planks and/or boards.

5.2 CARE AND STORAGE BEFORE INSTALLATION

BONDEK is delivered in strapped bundles. If not required forimmediate use stack sheets or bundles neatly and clear of theground, on a slight slope to allow drainage of water. If left in theopen, protect with waterproof covers.

30

5.3 INSTALLATION

5.3.1 PROPPINGDepending on the span of a bondek slab, temporary propping maybe needed between the slab supports to prevent excessivedeflections or collapse of the formwork.

BONDEK formwork is normally placed directly on prepared propping.Props must stay in place during the laying of BONDEK formwork, theplacement of the concrete, and until the concrete has reached thestrength of 15 MPa.

Propping generally consists of substantial timber or steel bearerssupported by vertical props. The bearers must be continuous acrossthe full width of BONDEK formwork.

Where the underside of bondek formwork is featured as a finishedceiling, wide form-ply strips attached to the bearers will minimisemarking. The width of the form-ply strips depends upon the slabdepth, BONDEK metal thickness and spans. Form-ply strips of 300 mmwidth have been used successfully.

Propping must be adequate to support construction loads and themass of wet concrete. The number of props you need for givenspans is shown in our tables.

5.3.2 LAYINGBONDEK must be laid with the sheeting ribs aligned in the direction of the designed spans. Other details include the following.

• The slab supports must be prepared for bearing and slip jointsas required.

• Lay BONDEK sheets continuously over each slab span without anyintermediate splicing or jointing.

• Lay BONDEK sheets end to end. Centralise the joint at the slabsupports. Where jointing material is required the sheets may bebutted against the jointing material.

• Support BONDEK sheets across their full width at the slab supportlines and at the propping support lines.

• For the supports to carry the wet concrete and constructionloads, the minimum bearing is 50 mm for ends of BONDEK sheets,and 100 mm for intermediate supports over which the sheetingis continuous.

• In exposed applications, treat the end and edges of the BONDEK sheets with a suitable edge treatment to prevent entry of moisture.

5.3.3 INTERLOCKING OF SHEETSOverlapping ribs of BONDEK sheeting are interlocked. Either of twomethods can be used in most situations, though variations may also work.

In the first method, lay adjacent sheets loosely in place. Place thefemale lap rib overlapping the male lap rib of the previous sheet andapply foot pressure, or a light kick, to the female lap rib (Figure 5.2).

In the second method, offer a new sheet at an angle to onepreviously laid, and then simply lower it down, through an arc (see Figure 5.2).

If sheets don’t interlock neatly (perhaps due to some damage ordistortion from site handling or construction practices) use screws to pull the laps together tightly (see Section 5.3.8, Fastening side-lap joints).

5.3.4 SECURING THE PLATFORMOnce laid, BONDEK provides a stable working platform. Whereadditional security is needed (to prevent movement fromconstruction activities and from wind) you can use:

• weights;

• screws or nails into the propping bearers; or

• BONWEDGE and BON-NUT suspension systems pulling down fromunderneath.

Take care if you use penetrating fasteners (such as screws and nails)because they can make removal of the props difficult, and perhapsresult in damage to the BONDEK.

5.3.5 INSTALLING BONDEK ON STEEL FRAMES

BONDEK may be installed directly on erected structural steelwork.

General fastening of bondekTo provide uplift resistance or lateral restraint, the sheeting may befixed to the structural steel using spot welds, or fasteners such asdrive nails or self-drilling screws.

At a movement joint, the sheeting is not continuous over thesupport. If one sheet is fastened at the joint, the other is not.

Place the fixings (fasteners and spot welds) in the flat areas of thepans adjacent to the ribs or between the flutes. The frequency offixings depends on wind or seismic conditions and good buildingpractice.

One fixing system is as follows.

• At the end of sheets: use a fixing at every rib (Figure 5.3).

• At each intermediate slab support over which the sheeting iscontinuous: use a fixing at the ribs on both edges (Figure 5.3).

• Fix BONDEK with drive nails, self-drilling screws or spot welds.

• Drive nails should be powder-activated, steel nails 4 mm nominaldiameter, suitable for structural steel of 4 mm thickness orgreater.

• For structural steel up to 12 mm thick, use 12-24 x 38 mm self-drilling hexagon head screws.

• For structural steel over 12 mm thick, pre-drill and use 12-24 x16 mm hexagon head screws.

• Spot welds should be 12 minimum diameter. Use 3.25 mmdiameter cellulose, iron powder AC/DC high penetrationelectrodes. Surfaces to be welded must be free of loose materialand foreign matter. Where the bondek soffit or the structuralsteelwork has a pre-painted surface, securing methods otherthan welding may be more appropriate. Take suitable safetyprecautions against fumes during welding zinc coated products.

Fastening composite beamsIn projects of composite beam construction the bondek sheetingmust be fastened in accordance with AS 2327, Clause 9.2(Composite beams with slabs incorporating profiled steel sheets).This provision requires a fixing in each pan at each composite beam.

Stud welding through the sheet has been considered a suitablesecuring method for the sheeting in a composite beam; howeversome preliminary fixing by one of the methods mentioned above isnecessary to secure the sheeting prior to the stud welding. Studwelding should comply with the requirements of AS 1554, Part 2and AS 2327, Part 1. Some relevant welding requirements are:

• Zinc coating on sheeting not to exceed Z450;

• Mating surfaces of steel beam and sheeting to be cleaned ofscale, rust, moisture, paint, overspray, primer, sand, mud orother contamination that would prevent direct contact betweenthe parent material and the bondek;

• Welding must be done in dry conditions by a certified welder;

• For pre-painted bondek sheets, special welding procedures maybe necessary; and

• For sheets transverse to beams, Stud welding must be betweenpan flutes to ensure there is no gap between mating surfaces.

5.3.6 INSTALLING BONDEK ON BRICK SUPPORTS

Brick walls are usually considered to be brittle and liable to crackfrom imposed horizontal loads. Thermal expansion and contraction,long-term shrinkage, creep effects and flexural deflection ofconcrete slabs may be sufficient to cause such cracking.

To prevent the cracking, BONDEK slabs are not usually installeddirectly on brick supports, although this is not always the case inearthquake construction.

Slip jointsGenerally, a slip joint is provided between bondek and masonrysupports (Figure 5.4).

• No fasteners are used between bondek and its support at a slipjoint.

• Slip joint material may be placed directly in contact with thecleaned surface of steelwork.

• The top course of masonry should be level, or finished with alevelled bed of mortar to provide an even bearing surface. Laythe top courses of bricks with the frogs facing down.

• The width of a slip joint should not extend beyond the face ofthe slab support.

• The slip joint material must have adequate compressive strengthto avoid it being compressed into irregularities of the matingsurfaces and thus becoming a rigid joint.

Slip joint material must allow movement to occur, usually by allowingflow under pressure or temperature, however it must not run orsolidify. Generically, the materials are a non-rotting, synthetic carrierimpregnated with a neutral synthetic or petroleum-based material.Typical slip joint material is Alcor (a bitumen coated aluminiummembrane).

5.3.7 INSTALLING BONDEK ON CONCRETE FRAMES

When used in concrete-frame construction, the BONDEK sheeting isdiscontinuous through the supports (Figure 5.5).

5.3.8 CONSTRUCTION AND MOVEMENT JOINTS

Joints used between BONDEK slabs generally follow acceptedconstruction practices. Construction joints are included between slabsfor the convenience of construction. Movement joints allow relativemovement between adjoining slabs. The joints may be transverse to,or parallel with, the span of the BONDEK slab. Movement joints need aslip joint under the BONDEK sheeting. (Figure 5.4).

Joints typically use a non-rotting, synthetic carrier impregnated witha neutral synthetic or petroleum based material like Malthoid (abitumen impregnated fibre-reinforced membrane). Sometimes asealant is used in the top of the joint for watertightness.

The BONDEK sheeting and any slab reinforcement are not continuous through a joint.

Design engineers generally detail the location and spacing of jointsbecause joints effect the design of a slab.

5.3.9 FASTENING SIDE-LAP JOINTSIf BONDEK sheeting has been distorted in transport, storage orerection, side-lap joints may need fastening to maintain a stableplatform during construction, to minimise concrete seepage duringpouring, and to gain a good visual quality for exposed soffits(Figure 5.6).

5.3.10 CUTTING AND FITTING EDGE FORM

EDGE FORM is a simple C-shaped section that simplifies the installationof most BONDEK slabs. It is easily fastened to the BONDEK sheeting,neatly retaining the concrete and providing a smooth top edge forquick and accurate screeding. We make it to suit any slab thickness.

EDGE FORM is easily spliced and bent to form internal and externalcorners of any angle and must be fitted and fully fastened as thesheets are installed. There are various methods of forming cornersand splices. Some of these methods are shown in Figures 5.7 and5.8.

Fasten EDGE FORM to the underside of unsupported BONDEK panelsevery 300 mm. The top flange of edge form must be tied to the ribsevery 600 mm with hoop iron 25 mm x 1.0 mm (Figures 5.7 and5.16). Use 10–16 x 16 mm self-drilling screws.

Make sure that the zinc coating on EDGE FORM matches the corrosion protection requirements of your job (see Section 1.10Corrosion protection).

5.3.11 SEALINGSeepage of water or fine concrete slurry can be minimised byfollowing common construction practices. Generally gaps are sealedwith waterproof tape or by sandwiching contraction joint materialbetween the abutting ends of BONDEK sheet. If there is a sizeablegap you may have to support the waterproof tape, and BONFILL maybe found useful (Figure 5.9).

5.3.12 ITEMS EMBEDDED IN SLABSGenerally use items in a manner which complies with AS 3600—2001, Clause 14.2 (Embedded items and holes in concrete), andClause 14.3 (Requirements for fixings). Included are pipes andconduits, sleeves, inserts, holding-down bolts, chairs and othersupports, plastic strips for plasterboard attachment, contraction jointmaterial and many more.

Table 5.1Location of items within the slab (Figure 5.10)

Minimise the quantity and size of holes through bondek sheeting, byhanging services from the underside of BONDEK using accessoriessuch as BON-NUT, BONWEDGE and CEILING SUSPENSION NUT.

5.3.13 HOLESBONDEK acts as longitudinal tensile reinforcement similarly toconventional bar or fabric reinforcement does in concrete slabs. Consequently,holes in BONDEK sheets, to accommodate pipes and ducts, reducethe effective area of the steel sheeting and can adversely effect theperformance of a slab.

Some guidelines for holes are (Figure 5.11):

• Place holes in the central pan of any sheet, with a minimumedge distance of 15 mm from the rib gap.

• Holes should be round, with a maximum diameter of 150 mm.

• For slabs designed as a continuous slab: space holes from an interior support of the slab no less than one tenth of a clear span.

5.3.14 INSPECTIONWe recommend regular qualified inspection during the installation,to be sure that the sheeting is installed in accordance with thispublication and with good building practice.

5.3.15 CUTTINGIt is easy to cut BONDEK sheets to fit. Use a power saw fitted with anabrasive disc or metal cutting blade. Initially lay the sheet with itsribs down, cut through the pans and part-through the ribs, then turnthe over and finish by cutting the tops of the ribs.

5.4 REINFORCEMENTBONDEK sheeting acts as longitudinal tensile reinforcement. The condition of sheeting should be inspected before concrete ispoured.

Reinforcement in slabs carries and distributes the design loads andto control cracking. Reinforcement is generally described astransverse and longitudinal in relation to span, but otherreinforcement required for trimming may be positioned in otherorientations. Figure 5.12 shows a typical cross-section of a BONDEK

composite slab and associated terms.

Reinforcement must be properly positioned, lapped where necessaryto ensure continuity, and tied to prevent displacement duringconstruction. Fix reinforcement in accordance with AS 3600—2001,Clause 19.2.5 (Fixing).

To ensure the specified minimum concrete cover, the uppermostlayer of reinforcement must be positioned and tied to preventdisplacement during construction (Section 3.4 Durability).

Splicing of conventional reinforcement must be in accordance withAS 3600—2001, Clause 13.2 (Splicing of reinforcement).

Where fabric is used in thin slabs, or where fabric is used to act asboth longitudinal and transverse reinforcement, pay particularattention the required minimum concrete cover and the requireddesign reinforcement depth at the splices—splice bars are a prudentaddition.

Always place chairs and spacers on pan areas. Depending upon thetype of chair and its loading, it may be necessary to use plates underchairs to protect the BONDEK, particularly where the soffit will beexposed. Transverse reinforcement may be used for spacing orsupporting longitudinal reinforcement.

5.4.1 TRANSVERSE REINFORCEMENTTransverse reinforcement is placed at right-angles to the ribs ofbondek. Deformed bar or fabric reinforcement may be used. In mostapplications the transverse reinforcement is for the control of crackscaused by shrinkage and temperature effects, and for locatinglongitudinal reinforcement.

To control flexural cracking in the top face of the slab, transversereinforcement in the top-face may be required over walls or beamswhich run in the same direction as the BONDEK sheets.

For ease of construction, reinforcement for control of cracking dueto shrinkage and temperature is usually fabric reinforcement (Section3.11.3, Crack control for flexure).

5.4.2 LONGITUDINAL REINFORCEMENTLongitudinal reinforcement is positioned to carry design loads in the same direction as the ribs of BONDEK. Deformed bar or fabricreinforcement may be used. Design information is in Chapters 2, 3and 4.

Top-face longitudinal reinforcement is usually located over interiorsupports of the slab and extends into approximately a third of theadjoining spans.

Bottom-face longitudinal reinforcement is located between supportsof the slab but, depending upon the detailing over the interiorsupports, it may be continuous, lapped, or discontinuous. Bottom-face longitudinal reinforcement may be placed on top of or belowtransverse reinforcement.

Location of bottom-face longitudinal reinforcement in elevatedtemperatures requires special design (Figures 4.5 and 4.6).

5.4.3 TRIMMERSTrimmers are used to distribute the design loads to the structuralportion of the slab and/or to control cracking of the concrete atpenetrations, fittings and re-entrant corners. Deformed bar or fabricreinforcement may be used.

Trimmers are sometimes laid at angles other than along or across thespan, and generally located between the top and bottom layers oftransverse and longitudinal reinforcement. Trimmers are generallyfixed with ties from the top and bottom layers of reinforcement.

5.5 CONCRETE

5.5.1 SPECIFICATIONThe concrete is to have the compressive strength as specified in the project documentation and the materials for the concrete and the concrete manufacture should conform to AS 3600—2001.

5.5.2 CONCRETE ADDITIVESAdmixtures or concrete materials containing calcium chloride or other chloride salts must not be used. Chemical admixtures including plasticisers may be used if they comply with AS 3600—2001, Clause 19.

5.5.3 PREPARATIONBefore concrete is placed, remove any accumulated debris, greaseor any other substance to ensure a clean bond with the BONDEK

sheeting. Remove ponded rainwater.

5.5.4 CONSTRUCTION JOINTSIt is accepted building practice to provide construction joints wherea concrete pour is to be stopped. Such discontinuity may occur as aresult of a planned or unplanned termination of a pour. A pour maybe terminated at the end of a day’s work, because of bad weather orequipment failure. Where unplanned construction joints are made,the design engineer must approve the position.

In certain applications, the addition of water stops may be required,such as in roof and balcony slabs where protection from corrosion ofreinforcement and sheeting is necessary.

Construction joints transverse to the span of the BONDEK sheeting arenormally located where shear forces are a minimum (such as the mid-third of a slab span) and ideally over a line of propping. Locatelongitudinal construction joints in the pan (Figure 5.13).

Form construction joints with a vertical face—the easiest technique isto sandwich a continuous reinforcement between two boards.

Prior to recommencement of concreting, the construction joint mustbe prepared to receive the new concrete, and the preparationmethod will depend upon the age and condition of the old concrete.Generally, thorough cleaning is required to remove loose material, toroughen the surface and to expose the course aggregate.

5.5.5 PLACINGThe requirements for the handling and placing of the concrete arecovered in AS 3600—2001, Clause 19.1.3 (Handling and placing ofconcrete).

The concrete is placed between construction joints in a continuous operation so that new concrete is placed against plastic concrete to produce a monolithic mass. If the pouring has to be discontinued forany more than approximately one hour, depending on thetemperature, a construction joint may be required.

Start pouring close to one end and spread concrete uniformly,preferably over two or more spans. It is good practice to avoidexcessive heaping of concrete and heavy load concentrations. Whenconcrete is transported by wheel barrows, the use of planks orboards is recommended.

During pouring, the concrete should be thoroughly compacted,worked around ribs and reinforcement, and into corners of the EDGE

FORMS by using a vibrating compactor. Ensure that the reinforcementremains correctly positioned so that the specified minimum concretecover is achieved.

Unformed concrete surfaces are screeded and finished to achievethe specified surface texture, cover to reinforcement, depths, falls orother surface detailing.

Surfaces which will be exposed, such as EDGE FORMS and exposedsoffits, should be cleaned of concrete spills while still wet, to reduce subsequent work.

5.5.6 CURINGAfter placement, the concrete is cured by conventional methods, forexample, by keeping the slab moist for at least seven days, bycovering the surface with sand, building paper or polythene sheetingimmediately after it has been moistened with a fine spray of water.Follow AS 3600—2001, Clause 19.1.5 (Curing and protection ofconcrete) and good building practice. Be particularly careful whencuring in very hot or very cold weather.

Until the concrete has cured, it is good practice to avoidconcentrated loads such as barrows and passageways with heavy traffic.

5.5.7 WHEN TO REMOVE PROPSVarious factors affect the earliest time when the props may beremoved and a slab initially loaded. Methods of calculating times andother guides are given in AS 3610—1995, Clause 5.4.3 (Stage III ofconstruction—Formwork stripping and after placement of concrete).

5.6 FINISHING

5.6.1 SOFFIT AND EDGE FORM FINISHESFor many applications, BONDEK gives an attractive appearance to theunderside (or soffit) of a composite slab, and will provide asatisfactory ceiling—for example, in car parks, under-house storageand garages, industrial floors and the like. Similarly, EDGE FORM willgive a suitable edging. Additional finishes take minimal extra effort.

Where the BONDEK soffit is to be the ceiling, take care during construction to minimise propping marks (refer to Installation—Propping), and to provide a uniform surface at the side-laps (refer toINSTALLATION—FASTENING SIDE-LAP JOINTS).

Exposed surfaces of BONDEK soffit and EDGE FORM may need cleaningand/or preparation for any following finishes. The cleaningpreparations are shown in Table 5.2.

Table 5.2Preparation of soffits and Edge Form

5.6.2 PAINTINGVarious painting systems are available for use with zinc coatings to provide a decorative finish and/or to provide an appropriatecorrosion protection system.

There are recommendations suitable for painting soffits and edges inPainting zinc-coated or zincalume steel sheet (BLUESCOPE LYSAGHT

technical information booklet). Field (on site) painting systems fromthat booklet are summarised in Table 5.3.

The performance of a paint system is influenced by the quality ofpreparation and application—closely follow the paint manufacturer’sinstructions.

For painted soffits, it may be preferable to cover the gaps of the ribsprior to painting. BONSTRIP snaps into the gaps of the ribs of theBONDEK sheeting and produces an attractive appearance (Figure 5.14).

The gap at the side-lap joint can be filled with a continuous bead ofsilicon sealant prior to painting.

5.6.3 PLASTERINGFinishes such as vermiculite plaster can be applied directly to theunderside of BONDEK with the open rib providing a positive key. Withsome products it may be necessary to treat the galvanised steelsurface with an appropriate bonding agent prior to application.

Plaster-based finishes can be trowelled smooth, or sprayed on togive a textured surface. They can also be coloured to suit interiordesign requirements.

5.6.4 CHANGE OF FLOOR LOADINGSWhere a building is being refurbished, or there is a change ofoccupancy and floor use, you may need to increase the fireresistance of the BONDEK composite slabs. This may be achieved by the addition of a suitable fire-protection material to the undersideof the slabs. The open ribs of BONDEK provide a positive key to keep the fire spray in position. Such work is beyond the scope of this manual.

5.7 SUSPENDED CEILINGS AND SERVICES

5.7.1 PLASTERBOARDA BONDEK soffit may be covered with plasterboard by fixing tobattens.

Fixing to battensSteel ceiling battens can be fixed directly to the underside of theslab using powder-actuated fasteners. The plasterboard is then fixedto ceiling battens in the usual way (Figure 5.15).

5.7.2 SUSPENDED CEILINGCeilings are easily suspended from bondek slabs using CeilingSuspension Nuts, BON-NUT suspension nuts, or BONWEDGE suspensionbrackets which comply with the load capacity requirements of AS2785. Threaded rods or wire hangers are then used to support theceiling. Alternatively, hangers may be attached to eyelet pinspowder-driven into the underside of the slab, or to pigtail hangersinserted through pilot holes in the BONDEK sheeting beforeconcreting (Figure 5.16).

5.7.3 SUSPENDED SERVICESServices such as fire sprinkler systems, piping and ducting are easilysuspended from BONDEK slabs using BON-NUT suspension nuts whichcomply with the load capacity requirements of AS2118 (Figure5.16).

6 WORKED EXAMPLES

EXAMPLE 1Design a three-span composite slab for steel-frame construction.

The crack control for flexure is not required, consequently twooptions may be considered (see Section 3.2). The reduced weight oflightweight concrete may be ignored (see Section 3.5.4). The ratio oflonger to shorter span length does not exceed 1.2, reinforcing bar is10 mm diameter, thus all necessary data can be read directly fromthe design tables.

Solution 1: Slab is designed as continuous for strength andserviceabilityThe data in the tables are applicable to both end and interior spans.

From the table on Page 104: D = 140 mm; 2 rows of propping; 480mm2 of negative reinforcement laid to standard Pattern 1 (Figure 3.1).

From the table on Page 105: additional fire (longitudinal)reinforcement of 360 mm2 must be placed as required for Fire Detail2 (Figure 4.5).

From Table 3.6, mesh SL62, laid on the top (Figure 1.1), may be used to control cracking due to temperature and shrinkage effects. Concrete cover is 20 mm.

Solution 2: Slab is designed as a series of simply-supportedslabs.From table on Page 68, Dcs = 170 mm; 2 rows of propping, nonegative reinforcement is necessary. From the table on Page 69:additional fire (longitudinal) reinforcement of 510 mm2 must beplaced as required for Fire Detail 2 (Figure 4.5)—the only option forsimply-supported slabs. The mesh SL72, laid on the bottom, may beused to control cracking due to temperature and shrinkage effects.

The choice between these two options may depend on which option is more economical.

EXAMPLE 2Design multiple-span composite slab for concrete-frame construction.

The ratio of longer to shorter span length does not exceed 1.2, thusall necessary data may be read directly from the design tables.

Support B

From the table on Page 116: Dcs = 190 mm for the end span (A–B); 2 rows of propping; 890 mm2 of negative reinforcement with bar 10 mm diameter, grade D500N only.

Span length must be 5.1 metres, so don’t consider length of interior span of 5.2 metres.

If the soffit is to be exposed, it is desirable to use form ply strips, 300 mm wide, for props to avoid localised damage to the BONDEK.

However, L-grade reinforcement was specified, thus the area ofnegative reinforcement must be increased for all support regionsbecause moment redistribution is not allowed for L-gradereinforcement (Section 3.10):

Ast– = 890 x 1.43 = 1273 mm2.

Proper compacting and placing of concrete is possible (Section 3.8.3). The negative reinforcement pattern is a standard one (Figure 3.1). The RL818 mesh, placed on top, may be used to control temperature and shrinkage effects.

Support A

The design of the top negative reinforcement (Figure 1.1) must bebased on rotational restraint provided by the end band-beam(similar to the left side of Figure 3.1); and can be takenconservatively as for Support B.

Supports DThe span length is taken as 4.5 m (maximum of 4.4 m, and 4.5 m). Our design tables would give a thickness less than 190 mm. You maydesign the slab with that reduced thickness or keep 190 mmthroughout. In both cases 820 mm2 of negative reinforcement isacceptable, though a bit conservative for 190 mm. A 160 mm optionwould require Pattern 2 of negative reinforcement (Figure 3.2).

Ast– = 820 x 1.43 = 1173 mm2

Note that the first interior span (B-C) must always have the samethickness as the end span.

Anchorage reinforcement: End support

w/L = (2 x 0.5) / 5.1 = 0.2 (Table 3.8)

Aanchorage = 0.23 x 890 = 205 mm2 (D500L or D500N)

Anchorage reinforcement: Support B

Aanchorage = 0.16 x 890 = 142 mm2

Anchorage reinforcement: Support D

Aanchorage = 0.16 x 820 = 131 mm2

For fire-rated buildings, the bottom fire reinforcement can also betreated as anchorage reinforcement.

To get a more economical design you could run BONDEK 2003,because our design tables were developed for steel-frame andmasonry-wall construction and don’t allow for the positive effect of band-beams on deflections and propping. BONDEK 2003 is likely to give:

• a thinner slab;

• less reinforcement for interior spans;

• slabs for interior spans may be designed thinner than end spans;

• less negative reinforcement required if D500N is specified forshrinkage reinforcement; and

• less temporary props.

EXAMPLE 3Design simply-supported slab for steel-frame construction.

Our Design Tables are worked out for normal weight concrete withsuperimposed dead load not exceeding 1 kPa. The superimposedload in this example is 3 kPa and must be transformed intoadditional live load as described in Section 3.5.5. This can be doneusing the advantage of light-weight concrete:

Additional Live load = (3 - 1 - (25 - 21) x 0.2) x 2 = 2.4 kPa (where Dcs = 200 mm - preliminary slab thickness from the table onPage 58).

Total transformed live load = 5.4 kPa.

From the table on Page 58: Dcs = 190 mm; 1 row of propping.

From the table on Page 59: additional fire (longitudinal)reinforcement of 460 mm2 (≥10 mm diameter, D500N) must beplaced as required for Fire Detail 2 (Figure 4.5)—the only option forsimply-supported slabs. The mesh RL818, placed on the bottom,may be used to control shrinkage and temperature effects.

9 BONDEK 2003 SOFTWARE

Our latest version – BONDEK 2003 software gives solutions thatconform to AS 3600—2001 Concrete structures.

The old version BONDEK 2000 was used to generate the design tablesin this book. BONDEK 2003 should be used to get more economicalsolutions, than you may get from the tables, because it offers manyadditional design options (see below).

Additional options

• Design with interior spans thinner than end spans

• Design of concrete-frame buildings with specified dimensions ofband beams and refined deflection calculations (slab thicknessthinner than given in the tables of Chapters 7 and 8)

• All reinforcement grades and bar diameters, in any combination, for negative, fire and shrinkage reinforcement

• An option of D500N grade for shrinkage reinforcement, whichsignificantly reduces the amount of fire and negativereinforcement (eliminates any need for these reinforcements forshort spans)

• Specified number of continuous spans (two-span, three-span etc.)

• Equal spans

• Lightweight concrete

• Superimposed dead load other than 1 kPa

• Option which checks your chosen slab thickness and designs therest of the parameters

• 20 MPa live load

• Fire rating of 4 hours

• Storage live loads (ψs = 1, ψl = 0.6)

• Design with no crack control requirements

• Design of formwork as continuous or discontinuous overpermanent supports

• A2 exposure classification

• Enhanced fire design
