ESSENTIAL NOTES - PRYDA PRODUCT GUIDES

The information in this Product Guide is provided for use in Australia by architects, engineers, building designers, builders and others. It is based upon the following criteria: 1. No Substitution: The products covered by or recommended in

this guide must not be substituted with other products. 2. Design Capacity Basis: See Codes & Standards following 3. Supporting Constructions: Constructions using Pryda

products must be built in accordance with the BCA or an appropriate Australian standard. Note: This includes appropriate corrosion protection- See Corrosion Protection following

4. Correct Installation: Installation of Pryda products must be strictly in accordance with the instructions in this guide

5. Current Guide Version Used: The current version of this guide, including any amendments or additions, must be used. Users are advised to check with Pryda for updates at least every three months by telephone, the web site: www.pryda.com.au or by email to: [email protected].

CODES & STANDARDS Product design capacities in this guide have been derived from: (a) results of laboratory tests carried out by or for Pryda Australia (b) engineering computations in accordance with the relevant

Australian standards, ie: * AS1720.1-1997 Timber Structures. Part 1: Design Methods * AS/NZS1170:2002 Structural Design Principles - or AS1170-

1989 SAA Loading Code * AS4055 -1992 Wind Loads for Housing Reference is also made to AS1684.1-1999 Residential Timber Framed Construction - Part 1: Design Criteria.

Design capacities tabulated in this guide apply directly for joints in houses and on secondary beams in other structures. For joints on primary beams in structures other than houses, reduce the capacity to 75% of the tabulated value. Design capacities are related to the Joint Group of the timber as defined in AS1720 and AS1684. If the joint group of timber members joined together varies, the lower group must be assumed for design, eg: JD5 is lower than JD4. Load Duration Factor for Wind Because AS/NZS1170:2002 reduces the design wind action (aka “load”) in many regions compared to AS1170-1989, Standards Australia has issued a draft amendment to AS1720.1-1997 which proposes a reduction in the duration of load factor for timber strength (k1) which, for fasteners, is from 1.3 to 1.15. This Guide therefore provides dual product design capacities, ie: 1. taking into account this proposed change 2. in accordance with the previous Loading Code and for use with

the wind uplift forces tabulated in AS1684. Users of this guide must, therefore, ascertain the standard used for determining the wind actions (loads) before selecting the appropriate wind load design capacity.

CORROSION PROTECTION Some Pryda structural connectors are hot dip galvanised to Z275 level. Others are hot dip galvanised after manufacture and some are made from Marine Grade (316) stainless steel. The Z275 zinc coating is adequate for Category A uses as defined in the BCA and tabulated below. For Category B uses (as per BCA), these products can be: (a) hot dip galvanised, (b) powder coated, or (c) stainless steel, all supplied to order. For detailed advice, contact a Pryda office.

companies and be of structural quality. 2. Connectors must not be installed on timber which is split before

or during installation. If the timber is likely to split as fasteners are driven, fastener holes must be pre-drilled.

3. Do not overload the joints- during construction or in service. 4. Bolt hole diameter must be 0.8 mm to 1.5 mm larger than the

bolt diameter and the specified washers must be installed. 5. Use proper safety equipment and due care in installing these

connectors 6. Any gaps in joints between the timber members must not

exceed 3 mm 7. Do not over-tighten screws. DEFINITIONS Special terms used in this guide are as defined in Australian standards, including: Design Capacity: the maximum Limit State Design load (aka “action”) which the product can safely support under the specified load condition, eg: dead + roof live load (1.2G + 1.5Q). Load case “Live” means dead + live load. Joint Group: classification of a timber according to its fastener-holding capacity.

BEAM HANGERSHeavy Brackets for Large Size Beams & I-joists

Beam Hanger for Beams Beam Hanger for I-

Joists Description Pryda Beam Hangers are heavy duty welded hangers for connection of large size beams or I-joists, ranging in thickness from 45 mm to 180 mm, to timber beams or masonry walls. Features Pryda Beam Hangers are: easy to install with a small number of coach screws and/or nails onto timber or with masonry anchors onto masonry or concrete

an economical means of forming these connections ideal for supporting heavily loaded beams on fire rated brick walls, eliminating the need for a girder truss or false wall to support the beams

additional top flange holes on two sizes to allow for easy casting into mortar joints

Hangers for I-joists support double I-joists Supply Beam Hangers are supplied individually. Dimensions Dimensions of Pryda Beam Hangers are shown below.

Design Capacities - General The loadbearing capacity of Pryda Beam Hangers depends on the criteria for each load direction as follows: Table D1. Downward Load Capacities

Load Load Design Criteria for: Direct-

ion Case Supporting

Beam/Ledger Supported

Beam

Down Dead load 16.2 kN Not critical

Live + Dead 22.8 kN Not critical

Wind down 31.4 kN Not critical

Up Wind up - Dead load

Withdrawal of fasteners

Shear at fixings

Notes: 1. The down direction loads are for:

(a) supporting member timber of JD5 joint group and SD6 strength group.

(b) Minimum supporting member size of 90x90 mm. 2. For JD4 and SD5 or higher joint/strength group

timber, these capacities can be increased by 25%. 3. For supporting member depths of less than 90 mm,

reduce design capacities in proportion to the depth divided by 90.

For joints on primary beams in structures other than houses, multiply these capacities by 0.75.

For bearing and uplift capacities of concrete or masonry walls, consult a structural engineer. Table D2 Supported Beam Bearing

I-JOIST HANGERSTop mount and face mount hangers for timber I-joists

Features Pryda I-Joist Hangers have features as follows:

Ideally suited to support of modern timber I-Joists.

Use of full depth hangers provides torsional restraint to the I-joist.

Dimples ensure correct alignment of nails into bottom flange of the I-joist to prevent squeaking. There is provision for a screw through the hanger into the bottom of the bottom flange to further reduce squeaking.

Description LT and LF types hangers are specifically designed for use with proprietary I-Joists such as Hybeam®, SmartFrame I-joist and Hyne I-Beam. LT type are for top fixing and LF for face fixing. LFVS are variable slope and skew. LFSL and LFSR are 45o degree skewed, left and right respectively. LVSIA type is a variable skew angle. Specification Dimensions are tabulated on the next page. All hangers are manufactured from G250, Z275 galvanised steel in 1.2 mm thickness, except for:

Notes: 1. LT & LF type I-joist Hangers are specifically designed for use with I

section floor joists such as Hybeam®, Smartframe Joist and Hyne I-beam.

2. LT hangers are top mount and LF are face mount. 3. LVSIA angles are 75x50x5 UA x 150 mm long. Installation - General To achieve the specified design loads, Pryda I-Joist Hangers must be correctly installed as specified in the following: 1. Refer to l-joist manufacturers’ instruction manuals for span

table selection and other details for on-site installation of their systems.

2. Use only galvanised Pryda Timber Connector Nails, Pryda product code OSNIB or OSNIB35. On 35 mm thick supporting members use 35x3.75 mm nails; on thicker members use 40x3.75 mm nails.

3. For screwing the joist to the hanger seat, use 30 x 6 gauge bugle-head or wafer-head wood screws.

4. All nail holes are to be filled with the specified nails in order to achieve hanger capacity.

Installation – Common Problems Poor or incorrect installation can lead to serious problems. Common problems are illustrated below: Note: See specified nail.

Nailplate is incorrect due to:1. Top plate is too thin, or2. Wrong length nail is usedTop nails

are missing

Top plateis too wide Incorrect

nailinstallation

If the top plate is too narrow it may cause:1. Hanger deformation2. Nail pull-out or shear3. Supported beam deformation

Joist is not seated properly into the hanger.This may cause nail pullout or shear under load.

Spreading hanger legs will push the joist upwhich may cause uneven floors, squeaky floors

and joist rotation Installation- Variable Skew Angles LVSIA variable skew angles are installed as shown in the following diagram, ie: 1. Notch the I-joist at ends to provide for fitting the LVSIA 2. Locate the angle with the 75 mm leg vertical and its mid-length

at the middle of the required end location of the I-joist. Fix the angle to the supporting beam, waling plate or ledger with 4@ 12g Type 17 screws. Screw length should be not less than that tabulated on the next page for the I-joist span and spacing.

3. Locate the I-joist on the angle and fix it up through the bottom of angle with 1@ 10g x 30 mm countersunk or bugle head screw.

4. Nail the I-joist top chord to the support with 2/75x3.05 mm nails.

Design Capacities Tabulated below are design capacities for Pryda I-joist Hangers fixed with the number of nails tabulated. “Face nails” are driven into the face of the supporting beam, “Top nails” into the top of the supporting beams and “Joist nails” into the carried member. General Notes 1. For uses in other than houses, reduce these capacities

by: - commercial/ industrial buildings- 6%, - essential services buildings - 12%.

2. Use only Pryda 40x3.75mm or 35x3.75 mm galvanisedPryda Timber Connector Nails, or equivalent.

3. “Dead” is dead load plus any portion of live loadconsidered to be permanent.

Face Mounted Hangers With a minimum of eight face nails, these hangers can carry the design residential floor loads of (1.5 kPa live) for joists up to 5.9 m span at 600 mm spacing or 7.9 m span at 450 mm spacing, provided that the timber in supporting beams has a joint group of JD4 or better. For other design cases, use the Pryda Connection Designer program.

Heavy Duty Joist Hanger for Large Sizes, Heavy Loads

General Description Pryda Joist Hangers, Split Joist Hangers and Heavy Duty Joist Hangers have been preferred and used in Australia and overseas for more than 20 years. They are strong, easy to install, cost effective, well designed connectors for many timber beam to beam joints. The wide range of these brackets provides for all common timber sizes and for glued laminated timber beams. These brackets have been designed to achieve high design loads at low cost through incorporating Pryda’s extensive design expertise and taking account of the results of laboratory testing at Monash University in Melbourne. Advantages In addition to being well designed and laboratory tested, Pryda Joist Hangers are: cost effective, eliminating the need for costly on-site skilled labour to make special housing for joints etc.

easily fixed into position with Pryda Timber Connector Nails, M12 bolts or self drilling screws. These hangers have wide flanges for ease of nailing.

Hanger Size Selection To establish a suitable Joist Hanger size, determine: 1. The joint group of the timber to be jointed.

Joint groups are specified in AS1720.1 SAA Timber Structures Code and in Pryda Timber Data. Groups for some timbers commonly used in Australia are:

Timbers Joint Group Dry GreenNorth American Oregon, western Hemlock JD4 J4 Heart-excluded Radiata pine and other softwoods JD4 J4 Pine as above – heart-in JD5 Slash pine JD3 J3 Ash type hardwoods from Victoria, NSW highlands and Tasmania

JD3 J3

Non-Ash type hardwoods from Queensland and NSW JD2 J2 Note: The moisture content of “dry” timber must not exceed 15%. Where beams of different joint groups are to be joined together, apply the lower group to both.

2. Loads to be supported. Applied loads are to be calculated in accordance with appropriate standards. Pryda Roof, Pryda Floor and Pryda Frame software output reaction loads which can be used for support bracket selection.

3. Thickness of beam, truss or joist to be supported and supporting beam thickness. When using JH code hangers (rather than JHS), the hanger’s bearing thickness must be up to 4 mm greater than that of the supported beam.

4. Fixing method: nails or bolts 5. Hanger size from the design load tables in this file based on the

above data.



Description This section covers properties of Pryda Joist Hangers, formerly known as Framing Brackets.

Features Pryda Joist Hangers are suitable for many joints including: - joist to beam - floor truss to beam - jack to TG truss - pergola rafters to fascia - ceiling joist to hanger - beams to masonry Installation Suitable Fasteners are: * Nails: Use only 35 x 3.15 mm, galvanised Pryda

Timber Connector Nails or Senco 50x2.87 mm hardened, roll threaded gun nails (Code: WGF21AZA) driven through the metal- not into the holes

* Bolts: M12 or ½ inch bolts with a nut and a 50x50x3.0 mm square or 55 mm dia.x3.0 mm round washer installed on the supporting beam on the face opposite to the hanger only.

Notes: 1. Beam A = Supporting, Beam B = Supported 2. Select wind uplift capacity according to the factor and, therefore,

the code used for the design loads/actions, ie: * 1.14 for AS/NZS1170:2002, * 1.3 for AS1170-1989 or AS1684-1999 3. Where both bolts and nails are used together, dead or live load

capacity = nails capacity + bolt(s) capacity, maximum: FB70200, FB90200 - 22.6 kN, all other brackets-26.9 kN.

4. These capacities apply directly for joints in houses and on secondary beams in other structures. For joints on primary beams in structures other than houses, multiply the capacity by 0.88.

5. For FB60130 and FB65170 brackets, wind uplift – dead load values have been reduced due to a shorter end distance on the supported beam compared to the other brackets.

6. For FB70200 to FB94152, the wind uplift 3 Nails fixing option allows for fixing to the chords only of I-beams or trusses.

Design Capacities – Bolt Fix Option The tabulated Limit State Design capacities apply directly to Pryda Truss Boot joints in houses or on secondary trusses or beams in other structures. For joints on primary trusses or beams in structures other than houses, multiply these capacities by 0.75. Girder timber thicknesses are minimums. Supported truss thicknesses are minimums for bolt capacity and maximums (3 mm tolerance for two nailplates) for fitting the timber into the boot. 70 and 90 mm thickness can be made from 2@ 35 mm and 2@ 45 mm respectively, nail or bolt laminated together as specified by the truss designer. Select the wind load design capacity in accordance with the factor and, therefore, the code used for the design loads, ie: * 1.14 for AS/NZS1170:2002 * 1.3 for AS1170-1989 or AS1684-1999 For joint groups other than those in the following tables, the following factors give a capacity which may be conservative.

2. For wind uplift, take the lower of the capacities for the supported truss and girder, ie: look up both tables above.



TRUSS BOOTS - MULTI-FIX- Screw Fix Option Metal brackets for timber construction

Truss Boot - Screw Fixed

Application & Features Pryda Multi-Fix Truss Boots comprise: Joist Boots -used for:

* End support of joists and beams * Support of lightly loaded trusses from girder trusses Truss Boots - used for support of standard trusses.

The Screw Fix option (fixing with screws only or nails only into supported member) avoids the need for anti-split plates and washers on bolts. Design capacities are somewhat lower than for Bolt Fix (see page 16). Pryda Truss Boots are designed to support trusses and other components 35-38mm or 45-48mm thick, carried by girders which are at least 35 mm thick. When the girder has multiple laminates, the same screws may be used but the plies must be nail or bolt laminated together as specified on the next page. Specification

TB35, TB45 TBJ70 Note: The inside dimension allows for the thickness of the supported timber plus two nailplates, eg: 38 mm allows for 35 mm timber + 2@ nailplates. Installation Generally, use the smaller holes present in the product and ignore all bolt holes. The Self Drilling wood screw (Code WTF12-35) will widen the hole in the Boot to the appropriate diameter to provide a tight fit. If a nailplate lies underneath the screw hole, the self drilling wood screw may be used if a nailplate hole is partially visible through the nail hole. Alternatively, use a Self Drilling steel screw (code WSF12-35) to drill through any nailplate. Where the roof is subject to little or no wind uplift, 35x3.15 mm galvanised Pryda Timber Connector Nails alone can be used to fix the supported truss- see Design Capacities next page. For screw fixing, Pryda Multi-Fix Truss Boots and supported members are to be installed as follows: 1. Fit the Boot flush with the bottom of the girder bottom

chord and power drive screws into all nail holes, ignoring the bolt holes. Do not over-tighten the screws. Any rubber or neoprene washer on the screw shank may be left in place and the screw is properly tightened when this washer squashes out to the same diameter as the integral metal washer.

2. Sit the incoming members into the Boot and hold in

place with screws, using a power screwdriver and the number of screws specified. Do not over-tighten screws. The clearance between the end of the ..



JOIST BOOTS & TRUSS BOOTS- Screw Fix Option - Continued incoming member and the face of the girder

truss chord should not exceed 5 mm. 3. The screws have been designed to

accommodate the twisting forces that are induced into this type of connection, and further “anti-rotation” devices are not necessary. Studies by Pryda show that anti-split nailplates are not required for these boots with screwed fixing, especially with softwood chords to the girders, but may still be required for other circumstances – refer to Pryda literature.

4. Care must be taken when screwing the boot onto a girder bottom chord. To minimise the risk of injury to the installer if the screwdriver slips, we recommend that an extender be used to provide greater clearance of the hands away from the Boot. This may not be necessary with the TBS types that are much shorter.

Anti-rotation legof Truss Boot

Carried truss

Features The long anti-rotation leg and heavy duty steel of Pryda Heavy Duty Truss Boots, combined with the inherent high stiffness of the carried truss, prevents twisting of the bottom chord of the girder. Consequently, anti-rotation bars are not necessary. Useful variations of this product have: the anti-rotation leg at 45 degrees for hip ends (../45) welded hinges to allow for any angle (TB80V)

Installation Pryda Heavy Duty Truss Boots are installed with 6@ M16 or 5/8 inch bolts and with 63x4 mm square washers on all surfaces where the bolt head or nut bears directly on the timber. Anti-split Claw nailplates are to be installed on both faces of the girder and on both sides of the truss boot (see Application above).

* 1.14 for AS/NZS1170:2002 * 1.3 for AS1170-1989 or AS1684-1999 3. Load case “Live” above means Live + Dead load and

“Wind” means Wind +/- Dead load. 4. For the TB80V boot, maximum loads are: Dead and live load: 26.4 kN; wind uplift: 17.8 kN 5. The Pryda Connection Designer software (included in

Pryda Frame) provides a quick and convenient means of determining whether a TB80 Truss Boot is suitable for specific design conditions.

Over-Angles & Over-Straps For uses where the wind uplift load exceeds the uplift capacity of the TB80, an over-angle or over-strap can be used. See the TB80 Uplift Reinforcement (next page). BOLT KITS FOR TRUSS BOOTS Hot dipped galvanised Kits of bolts, nuts and washers are available to suit all bolt fixed truss boots. Details are:

Notes: 1. The capacities for Detail-1 and Detail–3, with over-angle, are

limited by either top chord crushing against angle or 4/M16 bolts bearing on carrying truss or bending of outstanding leg of angle.

2. Select Uplift Capacity according to the version of the Loading Code used to compute the design wind loads, ie: AS1170-1989 or the version released in July 2002, ie: AS/NZS1170:2002.

3. The capacities for Detail-2 and Detail-4, with overstrap, are limited by either 4@ M16 bolts bearing on carrying truss or based on Details TD-06/TD-07 published by TRADAC (December 2000). For these tabulated capacities (details 2 & 4 only), the bolt through the over-strap must be installed through or above the heel joint nailplates.

4. The bottom chord of carrying truss shall be a minimum of 140 mm deep.

5. For Over-angle reinforcement, (Detail-1 or 3), Angle size is as tabulated below. For top chord pitches and top chord widths outside the scope of the above table, use over-angle size to suit. The minimum longer-leg (i.e bolted leg) dimension of the over-angle is governed by 25mm end distance for bolt, and the maximum dimension is limited by the over-angle being maintained flush to underside of truss bottom chord.

Equal angles of similar long-leg dimensions may be used as a substitute. Always bolt-fix through the longer-leg.

6. Fix the over-angle or over-strap to the TB80 with the M16 or 5/8 inch H.S bolt and nut used for fixing the TB80 to the carried truss. Install 63x5 mm square washers where the bolt or nut bears directly onto timber.
