KWIK HUS-EZ Screw Anchor Technical Supplement <br /> DESIGN INFORMATION IN CONCRETE PER CSA A23.3 <br /> Limit State Design of anchors is described in the provisions of CSA A23.3-14 Annex D for post-installed anchors tested and <br /> assessed in accordance with ACI 355.2 for mechanical anchors and ACI 355.4 for adhesive anchors. This section contains the <br /> Limit State Design tables with unfactored characteristic loads that are based on the published loads in ICC Evaluation Services <br /> ESR-3027.These tables are followed by factored resistance tables. The factored resistance tables have characteristic design <br /> loads that are prefactored by the applicable reduction factors for a single anchor with no anchor-to-anchor spacing or edge <br /> distance adjustments for the convenience of the user of this document.All the figures in the previous ACI 318-14 Chapter 17 <br /> design section are applicable to Limit State Design and the tables will reference these figures. <br /> For a detailed explanation of the tables developed in accordance with CSA A23.3-14 Annex D, refer to Section 3.1.8.Technical <br /> assistance is available by contacting Hilti Canada at(800)363-4458 or at www.hilti.com. <br /> Table 22-Steel resistance for Hilti KH-EZ, KH-EZ P, KH-EZ PM, KH-EZ PL, KH-EZ C and KH-EZ CRC <br /> carbon steel screw anchor'°2 <br /> Nominal <br /> anchor Tensile Shear Seismic shear' <br /> diameter Nominal embedment N V V <br /> sar sar sar,eq <br /> in. in.(mm) lb(kN) lb(kN) lb(kN) <br /> 1/4 1-5/8 2-1/2 3,370 855 770 <br /> (41) (64) (15.0) (3.8) (3.4) <br /> 1-5/8 2-1/8 5,475 2,030 2,030 <br /> 3/8 (41) (54) (24.4) (9.0) (9.0) <br /> 2-1/2 3-1/4 6,150 2,865 1,720 <br /> (64) (83) (27.4) (12.7) (7.7) <br /> 1/2 2-1/4 3 4-1/4 10,780 5,110 3,065 <br /> (57) (76) (108) (48.0) (22.7) (13.6) <br /> 5/8 3-1/4 4 5 14,405 6,200 3,720 <br /> (83) (102) (127) (64.1) (27.6) (16.5) <br /> 3/4 4 6-1/4 19,050 9,205 6,385 <br /> (102) (159) (84.7) (40.9) (28.4) <br /> 1 See PTG Ed.19 Section 3.1.8 to convert design strength value to ASD value. <br /> 2 Hilti KWIK HUS-EZ carbon steel screw anchors are to be considered brittle steel elements. <br /> 3 Tensile N =A5e N(Ps�,a R as noted in CSA A23.3-14 Annex D. <br /> 4 Shear determined by static shear tests with V <0.6 ASe V(�s fgra R as noted in CSA A23.3-14 Annex D. <br /> 5 Seismic shear values determined by seismic shear tests with Vsar.eq<_0.60 ASev 4)s f,R as noted in <br /> CSA A23.3-14 Annex D.See PTG Ed.19 Section 3.1.9 for additional information on seismic applications. <br /> KWIK HUS-EZ SCREW ANCHOR-July 2020 13 <br />
