Technical data

The technical data presented in this Anchor Fastening Technology Manual are all based onnumerous tests and evaluation according to the state-of-the art. Hilti anchors are tested in ourtest labs in Kaufering (Germany), Schaan (Principality of Liechtenstein) or Tulsa (USA) andevaluated by our experienced engineers and/or tested and evaluated by independent testinginstitutes in Europe and the USA. Where national or international regulations do not cover allpossible types of applications, additional Hilti data help to find customised solutions.

In addition to the standard tests for admissible service conditions and suitability tests, for safetyrelevant applications fire resistance, shock, seismic and fatigue tests are performed.

European Technical Approval Guidelines

Approval based data given in this manual are either according to European Technical ApprovalGuidelines (ETAG) or have been evaluated according to this guidelines and/or nationalregulations.

The European Technical Approval Guideline ETAG 001 METAL ANCHORS FOR USE INCONCRETE sets out the basis for assessing anchors to be used in concrete (cracked and non-cracked). It consists of:

Part 1 Anchors in general Part 2 Torque-controlled expansion anchors Part 3 Undercut anchors Part 4 Deformation-controlled expansion anchors Part 5 Bonded anchors Part 6 Anchors for multiple use for non-structural applications Annex A Details of test Annex B Tests for admissible service conditions detailed information Annex C Design methods for anchorages

For special anchors for use in concrete, additional Technical Reports (TR) related to ETAG 001set out additional requirements:

TR 018 Assessment of torque-controlled bonded anchors

TR 020 Evaluation of Anchorages in Concrete concerning Resistance to Fire TR 029 Design of Bonded Anchors

The European Technical Approval Guideline ETAG 020 PLASTIC ANCHORS FORMULTIPLE USE IN CONCRETE AND MASONRY FOR NON-STRUCTURAL APPLICATIONSsets out the basis for assessing plastic anchors to be used in concrete or masonry forredundant fastenings (multiple use). It consists of:

Part 1 General Part 2 Plastic anchors for use in normal weight concrete Part 3 Plastic anchors for use in solid masonry materials Part 4 Plastic anchors for use in hollow or perforated masonry

Part 5 Plastic anchors for use in autoclaved aerated concrete (AAC) Annex A Details of tests Annex B Recommendations for tests to be carried out on construction works Annex C Design methods for anchorages


22/850

Legal environment

10 / 2012 21

The European Technical Approval Guidelines including related Technical Reports set out therequirements for anchors and the acceptance criteria they shall meet.

The general assessment approach adopted in the Guideline is based on combining relevant

existing knowledge and experience of anchor behaviour with testing. Using this approach,testing is needed to assess the suitability of anchors.

The requirements in European Technical Approval Guidelines are set out in terms of objectivesand of relevant actions to be taken into account. ETAGs specify values and characteristics, theconformity with which gives the presumption that the requirements set out are satisfied,whenever the state of art permits to do so. The Guidelines may indicate alternate possibilitiesfor the demonstration of the satisfaction of the requirements.

Post-installed rebar connections

The basis for the assessment of post-installed rebar connections is set out in the TechnicalReport

TR 023 Assessment of post-installed rebar connections

The Technical Report TR 023 covers post-installed rebar connections designed in accordancewith EN 1992 - 1-1: 2004 (EC2) only. ETAG 001 (Part 1 and Part 5) is the general basic of thisapplication. The Technical Report TR 023 deals with the preconditions, assumptions and therequired tests and assessments for postinstalled rebars.

System of attestation of conformity

For anchors having an approval, the conformity of the product shall be certified by an approvedcertification body (notified body) on the basis of tasks for the manufacturer and tasks for theapproved body.

Tasks for the manufacturer are: Factory production control (permanent internal control of production and documentation

according to a prescribed test plan) involve a body which is approved for the tasks

Tasks for the approved body are: initial type-testing of the product

initial inspection of factory and of factory production control continuous surveillance, assessment and approval of factory production control

Base material

General

Different anchoring conditions The wide variety of building materials used today provide differentanchoring conditions for anchors. There is hardly a base material in or towhich a fastening cannot be made with a Hilti product. However, theproperties of the base material play a decisive role when selecting asuitable fastener / anchor and determining the load it can hold.

The main building materials suitable for anchor fastenings have beendescribed in the following.

Concrete

A mixture of cement,

aggregates and water

Concrete is synthetic stone, consisting of a mixture of cement, aggregates

and water, possibly also additives, which is produced when the cementpaste hardens and cures. Concrete has a relatively high compressivestrength, but only low tensile strength. Steel reinforcing bars are cast inconcrete to take up tensile forces. It is then referred to as reinforcedconcrete.

Cracking from bending

Stress and strain in sectionswithconditions I and II

b, D calculated compressive stressb, Z calculated tensile stressfct concrete tensile strength

If cracks in the tension zoneexist, suitable anchor systemsare required

If the tensile strength of concrete is exceeded, cracks form, which, as arule, cannot be seen. Experience has shown that the crack width does notexceed the figure regarded as admissible, i.e. w 0.3mm, if the concrete is

under a constant load. If it is subjected predominately to forces ofconstraint, individual cracks might be wider if no additional reinforcement isprovided in the concrete to restrict the crack width. If a concrete componentis subjected to a bending load, the cracks have a wedge shape across thecomponent cross-section and they end close to the neutral axis. It isrecommended that anchors that are suitable in cracked concrete be used inthe tension zone of concrete components. Other types of anchors can beused if they are set in the compression zone.

Observe curing of concretewhen using expansionanchors

Anchors are set in both low-strength and high-strength concrete. Generally,the range of the cube compressive strength, fck,cube, 150, is between 25 and60 N/mm. Expansion anchors should not be set in concrete which has notcured for more than seven days. If anchors are loaded immediately after

they have been set, the loading capacity can be assumed to be only theactual strength of the concrete at that time. If an anchor is set and the loadapplied later, the loading capacity can be assumed to be the concretestrength determined at the time of applying the load.

Cutting through reinforcement when drilling anchor holes must be avoided.If this is not possible, the design engineer responsiblemust be consultedfirst.

Avoid cutting reinforcement

Masonry

Masonry is a heterogeneous base material. The hole being drilled for ananchor can run into mortar joints or cavities. Owing to the relatively lowstrength of masonry, the loads taken up locally cannot be particularly high.A tremendous variety of types and shapes of masonry bricks are on themarket, e.g. clay bricks, sand-lime bricks or concrete bricks, all of differentshapes and either solid or with cavities. Hilti offers a range of differentfastening solutions for this variety of masonry base material, e.g. the HPS-1, HRD, HUD, HIT, etc.

If there are doubts when selecting a fastener / anchor, your local Hilti salesrepresentative will be pleased to provide assistance.

Different types and shapes

When making a fastening, care must be taken to ensure that a lay ofinsulation or plaster is not used as the base material. The specifiedanchorage depth (depth of embedment) must be in the actual basematerial.

Plaster coating is not a basematerial for fastenings

Other base materials

Aerated concrete: This is manufactured from fine-grained sand as theaggregate, lime and/or cement as the binding agent, water and aluminiumas the gas-forming agent. The density is between 0.4 and 0.8 kg/dm andthe compressive strength 2 to 6 N/mm. Hilti offers the HGN and HRD-Uanchors for this base material.

Aerated concrete

Lightweight concrete: This is concrete which has a low density, i.e. 1800kg/m, and a porosity that reduces the strength of the concrete and thus theloading capacity of an anchor. Hilti offers the HRD, HUD, HGN, etc anchorsystems for this base material.

Lightweight concrete

Drywall (plasterboard/gypsum) panels: These are mostly buildingcomponents without a supporting function, such as wall and ceiling panels,to which less important, so-called secondary fastenings are made. The Hiltianchors suitable for this material are the HTB, HLD and HHD.

Drywall / gypsum panels

In addition to the previously named building materials, a large variety ofothers, e.g. natural stone, etc, can be encountered in practice. Further-more, special building components are also made from the previously

mentioned materials which, because of manufacturing method andconfiguration, result in base materials with peculiarities that must be givencareful attention, e.g. hollow ceiling floor components, etc.

Descriptions and explanations of each of these would go beyond thebounds of this manual. Generally though, fastenings can be made to thesematerials. In some cases, test reports exist for these special materials. It isalso recommended that the design engineer, company carrying out thework and Hilti technical staff hold a discussion in each case.

Variety of base materials

In some cases, testing on the jobsite should be arranged to verify thesuitability and the loading capacity of the selected anchor.

Why does an anchor hold in a base material?

Working principles

There are three basic working principles which make an anchor hold in a building material:

Friction The tensile load, N, is transferred tothe base material by friction, R. Theexpansion force, Fexp, is neces-sary for this to take place. It is pro-duced, for example, by driving in anexpansion plug (HKD).

Keying The tensile load, N, is in equilibriumwith the supporting forces, R, acting

on the base material, such as withthe HDA anchor.

Bonding An adhesive bond is producedbetween the anchor rod and thehole wall by a synthetic resinadhesive, such as with HVU withHAS anchor rods.

Combination of workingprinciples

Many anchors obtain their holding power from a combination of the abovementioned working principles.

For example, an anchor exerts an expansion force against wall of its hole

as a result of the displacement of a cone relative to a sleeve. This permitsthe longitudinal force to be transferred to the anchor by friction. At the sametime, this expansion force causes permanent local deformation of the basematerial, above all in the case of metal anchors. A keying action resultswhich enables the longitudinal force in the anchor to be transferredadditionally to the base material

Force-controlled anddisplacement-controlledexpansion anchors

In the case of expansion anchors, a distinction is made between force-controlled and movement-controlled types. The expansion force of force-controlled expansion anchors is dependent on the tensile force in theanchor (HSL-3 heavy-duty anchor). This tensile force is produced, and thuscontrolled, when a tightening torque is applied to expand the anchor.

In the case of movement-controlled types, expansion takes place over a

distance that is predetermined by the geometry of the anchor in theexpanded state. Thus an expansion force is produced (HKD anchor) whichis governed by the modulus of elasticity of the base material.

Adhesive/resin anchor The synthetic resin of an adhesive anchor infiltrates into the pores of thebase material and, after it has hardened and cured, achieves a local keyingaction in addition to the bond.

Failure modes

Effects of static loading

The failure patterns of anchor fastenings subjected to a continuallyincreased load can be depicted as follows:

Failure patterns

1. 2.

3. 3a.

4.

The weakest point in an anchor fastening determines the cause of failure.Modes of failure, 1. break-out, 2. anchor pull-away and, 3., 3a., failure ofanchor parts, occur mostly when single anchors that are a suitable distancefrom an edge or the next anchor, are subjected to a pure tensile load.These causes of failure govern the max. loading capacity of anchors. Onthe other hand, a small edge distance causes mode of failure 4. edgebreaking. The ultimate loads are then smaller than those of the previouslymentioned modes of failure. The tensile strength of the fastening basematerial is exceeded in the cases of break-out, edge breaking and splitting.

Causes of failure

Basically, the same modes of failure take place under a combinedload. Themode of failure 1. break-out, becomes more seldom as the angle betweenthe direction of the applied load and the anchor axis increases.

Combined load

Generally, a shear load causes a conchoidal (shell-like) area of spall onone side of the anchor hole and, subsequently, the anchor parts sufferbending tension or shear failure. If the distance from an edge is small andthe shear load is towards the free edge of a building component, however,the edge breaks away.

Influence of cracks

Very narrow cracks are not

defects in a structure

It is not possible for a reinforced concrete structure to be built which doesnot have cracks in it under working conditions. Provided that they do not

exceed a certain width, however, it is not at all necessary to regard cracksas defects in a structure. With this in mind, the designer of a structureassumes that cracks will exist in the tension zone of reinforced concretecomponents when carrying out the design work (condition II). Tensile forcesfrom bending are taken up in a composite construction by suitably sizedreinforcement in the form of ribbed steel bars, whereas the compressiveforces from bending are taken up by the concrete (compression zone).

Efficient utilisation ofreinforcement

The reinforcement is only utilised efficiently if the concrete in the tensionzone is permitted to be stressed (elongated) to such an extent that it cracksunder the working load. The position of the tension zone is determined bythe static / design system and where the load is applied to the structure.Normally, the cracks run in one direction (line or parallel cracks). Only in

rare cases, such as with reinforced concrete slabs stressed in two planes,can cracks also run in two directions.

Testing and application conditions for anchors are currently being draftedinternationally based on the research results of anchor manufacturers anduniversities. These will guarantee the functional reliability and safety ofanchor fastenings made in cracked concrete.

Loadbearing mechanisms When anchor fastenings are made in non-cracked concrete, equilibrium isestablished by a tensile stress condition of rotational symmetry around theanchor axis. If a crack exists, the loadbearing mechanisms are seriouslydisrupted because virtually no annular tensile forces can be taken upbeyond the edge of the crack. The disruption caused disrupted by the crackreduces the loadbearing capacity of the anchor system.

a) Non-cracked concrete

Crack plane

b) Cracked concrete

Reduction factor for cracked

concrete

The width of a crack in a concrete component has a major influence on the

tensile loading capacity of all fasteners, not only anchors, but also cast-initems, such as headed studs. A crack width of about 0.3mm is assumedwhen designing anchor fastenings. The reduction factor which can be usedfor the ultimate tensile loads of anchor fastenings made in cracked concreteas opposed to non-cracked concrete may be assumed to be 0.65 to 0.70for the HSC anchor, for example. Larger reduction factors for ultimatetensile loads must be anticipated (used in calculations) in the case of allthose anchors which were set in the past without any consideration of theabove-mentioned influence of cracks. In this respect, the safety factor touse to allow for the failure of cracked concrete is not the same as the figuregiven in product information, i.e. all previous figures in the old anchormanual. This is an unacceptable situation which is being eliminated throughspecific testing with anchors set in cracked concrete, and adding suitable

information to the product description sheets.


34/850

Base materials

10 / 2012 33

Since international testing conditions for anchors are based on the above-mentioned crack widths, no theoretical relationship between ultimate tensileloads and different crack widths has been given.

The statements made above apply primarily to static loading

conditions. Ifthe loading is dynamic, the clamping force and pretensioning force in ananchor bolt / rod play a major role. If a crack propagates in a reinforcedconcrete component after an anchor has been set, it must be assumed thatthe pretensioning force in the anchor will decrease and, as a result, theclamping force from the fixture (part fastened) will be reduced (lost). Theproperties of this fastening for dynamic loading will then have deteriorated.To ensure that an anchor fastening remains suitable for dynamic loadingeven after cracks appear in the concrete, the clamping force andpretensioning force in the anchor must be upheld. Suitable measures toachieve this can be sets of springs or similar devices.

As a structure responds to earthquake ground motion it experiencesdisplacement and consequently deformation of its individual members. This

deformation leads to the formation and opening of cracks in members.Consequently all anchorages intended to transfer earthquake loads shouldbe suitable for use in cracked concrete and their design should bepredicted on the assumption that cracks in the concrete will cycle open andclosed for the duration of the ground motion.

Parts of the structures may be subjected to extreme inelastic deformation.In the reinforced areas yielding of the reinforcement and cycling of cracksmay result in cracks width of several millimetres, particularly in regions ofplastic hinges. Qualification procedures for anchors do not currentlyanticipate such large crack widths. For this reason, anchorages in thisregion where plastic hinging is expected to occur, such as the base ofshear wall and joint regions of frames, should be avoided unless apposite

design measures are taken.

Design methods

Metal anchors for use in concrete according ETAG 001

The design methods for metal anchors for use in concrete are described in detail in Annex C of the EuropeanTechnical Approval guideline ETAG 001 and for bonded anchors with variable embedment depth in EOTATechnical Report TR 029. Additional design rules for redundant fastenings are given in Part 6 of ETAG 001.

The design method given in this Anchor Fastening Technology Manual is based on these guidelines. Thecalculations according to this manual are simplified and lead to conservative results, i.e. the results are on the saveside. Tables with basic load values and influecing factors and the calculation method are given for each anchor inthe respective section.

Anchors for use in other base materials and for special applications

If no special calculation method is given, the basic load values given in this manual are valid, as long as theapplication conditions (e.g. base material, geometrie, environmental conditions) are observed.

Redundant fastenings with plastic anchors

Design rules for redundant fastings with plastic anchors for use in concrete and masonry for non-structuralapplications are given in Annex C of ETAG 020. The additional design rules for redundant fastenings areconsidered in this manual.

Resistance to fi re

When resistance to fire has to be considered, the load values given in the section resistance to fire should beobserved. The values are valid for a single anchor.

Hilti design software PROFIS Anchor

For a more complex and accurate design according to international and national guidelines and for applicationsbeyond the guidelines, e.g. group of anchors with more than four anchors close to the edge or more than eightanchors far away from the edge, the Hilti design software PROFIS Anchor yields customised fastening solutions.The results can be different from the calculations according to this manual.

The following methods can be used for design using PROFIS Anchor:

- ETAG

- CEN/TS

- ACI 318-08

- CSA (Canadian standard)

- Solution for Fastening (Hilti internal design method)

anchors or more than one edge. The influencing factors must then be considered for each edge distanceand spacing. The calculated design loads are then on the save side: They will be lower than the exactvalues according ETAG 001, Annex C. To avoid this, it is recommended to use the anchor design softwarePROFIS anchor)

General remarks

According EOTA Technical Report TR 029, concrete cone, combined concrete cone and pull-out, splitting, pryoutand concrete edge design resistance must be verified for the anchor group. Steel design resistance must beverified for the most unfavourable anchor of the anchor group.

According to the simplified design method given in this Fastening Technology Manual all anchors of a group areloaded equally, the design resistance values given in the tables are valid for one anchor.
