38、nstitute Copyrighted Materialwww.concrete.orgCHAPTER 1INTRODUCTION1.1IntroductionThis standard prescribes testing and evaluation requirementsfor post-installed adhesive anchor systems intended for usein concrete under the provisions of ACI 318M. Criteria areseparately prescribed to determine the sui

39、tability of adhesiveanchors used in uncracked concrete only, or in both crackedand uncracked concrete. Criteria are prescribed to determinethe design parameters and performance category for adhesiveanchors. Included are assessments of the adhesive anchorsystem for bond strength, reliability, service

40、 conditions, andquality control. Special inspection (13.3) is required duringanchor installation as noted in 10.22. Table 1.1 provides anoverview of the scope.R1.1 This standard prescribes the testing programsrequired to qualify post-installed adhesive anchor systemsfor design in accordance with ACI

41、 318M, Appendix D.Appendix D requires that anchors be tested either for useexclusively in uncracked concrete or for use in cracked anduncracked concrete conditions, whereby it is understood thatthe presence of cracking may occur at any time over theservice life of the anchors. Test and assessment cr

42、iteria areprovided for various conditions, including loads (seismicand sustained), environmental with regard to humidity andtemperature, and determination if anchors are acceptablefor use in cracked or uncracked concrete. Refer to Cook andKonz (2001) for a review of factors that influence adhesivean

43、chor behavior. Refer to Fuchs et al. (1995) for backgroundon the concrete breakout design model and to Eligehausen etal. (2006) and Zamora et al. (2003) for a discussion of bondmodels for adhesive and grouted anchors. For a discussionof issues associated with the qualification and design ofsystems f

44、or post-installed reinforcing bars, refer to Spieth etal. (2001).1.2ScopeThis standard applies only to post-installed adhesiveanchors as defined herein.R1.2 Adhesive anchors resist tension loads with a combi-nation of adhesion and mechanical bond (micro-interlock).Different anchor designs and adhesi

45、ve types may exhibit arange of performance characteristics. In particular, thesensitivity of adhesive anchors to variations in installationand service-condition parameters (such as hole cleaning,installation orientation, and cracked concrete characteristics)may vary widely from each system. ACI 318M

46、 addresses thissituation by matching capacity reduction factors to anchorperformance categories that are, in turn, establishedthrough a series of reliability tests.1.2.1 This standard applies to anchors with a diameter daof 6 mm or larger. The drilled hole shall be approximatelycylindrical with a di

47、ameter do 1.5da. This standard alsoapplies to anchors with an anchor embedment depth hefnotless than four diameters (4da), or 41 mm, and an embedmentdepth not exceeding 20da.R1.2.1 The minimum diameter of 6 mm is based onpractical considerations regarding the limit of structuralanchor applications.

48、The upper limit on the ratio of holediameter to anchor element diameter provides a demarcationbetween conditions where a single bond strength can be usedto evaluate anchor strength and conditions where bondstrengths at both the anchor interface and concrete interfacemust be determined to evaluate an

49、chor strength. In addition,the value of 1.5dais based on consideration of typical practicewhereby most organic adhesives are used with thin bondlines to limit both adhesive shrinkage and creep of theanchor when under load. The design method deemed tosatisfy the anchor design requirements of ACI 318M,Appendix D, is based on an analysis of an anchor databasewith a maximum diameter of 50.8 mm. While ACI 355.4Mgives no limitations on maximum anchor diameter, foranchors beyond
