Compare to the steel values in table 22. <br /> The lesser of the values is to be used for the design. <br /> 4 Tabular values are for normal-weight concrete only. For lightweight concrete multiply design strength by Aa as follows: <br /> for sand-lightweight,A.=0.68;for all-lightweight,ha =0.60 <br /> 5 Tabular values are for static loads only.Seismic design is not permitted for uncracked concrete.For seismic tension loads,multiply <br /> cracked concrete tabular values in tension by the following reduction factors: <br /> 1/4-inch diameter-a =0.60 <br /> 3/8-inch diameter-ar,,,.,,=0.75. <br /> No reduction needed for seismic shear.See PTG Ed.19 Section 3.1.8 for additional information on seismic applications. <br /> KWIK HUS-EZ SCREW ANCHOR-July 2020 17 <br />
