Significance and Use4.1 These t

17、est methods are intended to measure the anchor-ing capability and shear resistance of power-actuated fastenersto provide information from which applicable design values areto be derived for use in structural applications, such as inmembers of concrete, concrete masonry, and steel.5. Apparatus5.1 Equ

18、ipmentAny system suitable for applying tensileand shear forces shall be used, provided the requirements forrate of loading in 9.4 are met, and the instrumentation iscapable of measuring the forces to an accuracy within 6 2%of the applied force, when calibrated in accordance withPractices E4. The dev

19、ice shall be of sufficient capacity toprevent yielding of its various components and shall ensurethat the applied tensile forces remain parallel to the axes of thefasteners and that the applied shear forces remain parallel to thesurface of the structural member during testing. Load cellsshall be use

20、d for laboratory testing. If pressure gages are usedfor field testing, they shall be calibrated immediately prior touse.5.1.1 Tensile TestA system suitable for applying tensileforces is shown in Fig. 1 for a single fastener specimen. Thetest system supports shall be of sufficient size to prevent fai

21、lureof the surrounding structural member. The loading rod shall beof a size to develop the ultimate strength of the fastenerhardware with minimal elongation and shall be attached to thefastener by means of a connector that will minimize the directtransfer of bending forces through the connection. Wh

22、endisplacements are measured, dial gages or a linear variabledifferential transformer (LVDT) shall be mounted in a mannerso as to ensure accurate displacement measurement.5.1.2 Shear Test:5.1.2.1 Asystem suitable for applying shear forces is shownin Fig. 2. for a single fastener specimen. The compon

23、ents of thetest fixture shall be of sufficient size and strength to preventyielding during application of the ultimate test load. The testsystem support shall be of sufficient size to prevent local failureof the structural member in the bearing contact area. Whendisplacements are measured, dial gage

25、rsection of thefastener and the base material unless otherwise specified. Thehole in the shear fixture designed to accommodate the fastenershall have a diameter that is 0.5 6 0.1 mm (0.020 6 0.004 in.)FIG. 1 Typical Static Tension Test ArrangementE1190 112greater than that of the fastener shank diam

The loadingend of the slot shall have a width that is 0.5 6 0.1 mm(0.020 6 0.004 in.) greater than that of the fastener shankdiameter tested. The non-loading end of the sl

27、ot is permitted tobe larger than the fastener head or thread diameter. The initialshape of the hole or the loading end of the slot in the shearfixture shall correspond to that of the fastener shank crosssection and shall be maintained throughout all tests. For shearfixtures using a slot to accommoda

28、te the fastener instead of ahole, loading is to be applied parallel to the slot. Worn ordeformed holes or slots shall be repaired. When required, insertsleeves shall be installed in the shear plate to meet theserequirements, provided they do not increase deformation of theanchorage under load.5.2 Op

29、tional Displacement Measurements Displacementor deformation measurements are not required to derive designdata for a given fastening system.5.2.1 Tension Test (see Fig. 1)Dial gages, having asmallest division of not more than 0.025 mm (0.001 in.), or anysuitable measurement devices or calibrated sen

30、sors of at leastcomparable accuracy and sensitivity, such as an LVDT, shall beused to measure displacement of the fastening system relativeto the structural member. The instruments shall be positionedto measure the vertical movement of the fastener with respectto points on the structural member, at

31、a minimum distance of40 mm (1.6 in.) from the center of the test fastener. Theinstruments shall be mounted on the fastener specimen orloading rod at a distance not more than 100 mm (4.0 in.) fromthe structural member surface, in order to minimize extraneousmovements (hardware elongation) in the disp

32、lacement mea-surements.5.2.2 Tests of a Group of Fasteners Only one set ofinstruments is required for a group of fasteners tested as aclosely spaced cluster. The displacement to be used for theevaluation of the findings is the average deformation indicatedby all instruments mounted symmetrically equ

33、idistant from thecenter of the cluster.5.2.3 Shear Test (see Fig. 2)A single dial gage, having asmallest division of not more than 0.025 mm (0.001 in.) or anysuitable measurement device, such as an LVDT, or calibratedsensor of at least comparable accuracy and sensitivity shall beused to measure the

34、displacement of the fastening systemrelative to the structural member. The instrument shall bepositioned to measure displacement in the direction of theapplied force. The displacement sensor shall be placed on thestructural member to allow the sensing element to be in directcontact with the fastener

35、 or be attached directly to the fastener.For tests on clusters of fasteners, the instrument shall lie in aplane through the axis of the shear loading rod or plate. Anextension of the axis of the shear fixture shall pass through thecentroid of the cluster of fasteners.6. Hazards6.1 Take precaution to

39、-cepted field methods or to meet the requirements of the tests.7.3 Fastener PlacementAll fasteners (types, sizes, em-bedment depths) to be used in a given installation shall eitherbe tested individually or in groups of two or more at theintended spacing. Fasteners shall be installed at distances equ

40、alto or greater than those specified in Table 1 to precludeinfluences from adjacent fasteners or edges during testing.These distances are not to be considered minimum distances.Tests shall be performed to determine minimum spacing andedge distances.7.4 Structural MemberThe structural member in which

41、the fastener is to be installed shall be representative of thematerials and configuration intended for field use. Concrete ormasonry structural members do not have to be reinforced withsteel (Note 1).NOTE 1The location and orientation of reinforcement embedded inconcrete and masonry members may infl

42、uence fastener capacity. Theirinfluence shall be evaluated if reinforcement is used.7.5 The concrete or masonry structural member thickness,T, shall be sufficient to ensure that the installation and testingof the fastener will not crack or cause any other failure of thebase material.7.6 The length,

43、L, and width, W, of concrete structuralmembers shall ensure that no shear breakout or tension failurespall intersects either the outside edges of the structuralmember or the bearing contact points of the test frame.7.7 The edge distance, c, shall be as in Table 1 where thereaction bridge in the shea

44、r test set-up shown in Fig. 2 providesa minimum 150-mm (5.9-in.) clearance along the edge of theconcrete structural member and a minimum 50-mm (2.0-in.)clearance along the edge of a steel structural member (notshown). A shear reaction bridge is not required when concreteedge distances exceed 150 mm

45、or steel edge distances exceed50 mm.7.8 When testing fasteners installed in horizontal mortarjoints, the masonry wall shall be treated as a completestructural member.

Number of Tests8.1 Tensile or Shear ResistanceFor determining the aver-age tensile or shear resistance, perform at least the minimumnumber of tests per condition specified

47、 in Table 2. Dependingon the purpose of the test, the number of tests shall beincreased. These tests shall be repeated for each variation infastener type, size, embedment depth, location, and for eachvariation in the type or strength of structural member. Alter-natively, if the sample size is ten an

48、d the coefficient of variationis 15 % or greater, the fastener capacity shall be based on thelowest test value for the original ten tests instead of increasingthe sample size.8.2 All installed fasteners shall be tested regardless offastener embedment, angle of installation, damage to thestructural m

49、ember, or damage to the fastener. Fasteners thatcannot be tested, because they did not set at all, that is were notinstalled properly, shall be reported as invalid data points.Invalid data points shall not be included when determining theaverage ultimate test values.8.3 For developing minimum edge distances and fastenerspacings, the number of fasteners for each condition shall be atleast ten.9.
