<br /> 1 See PTG Ed.19 Section 3.1.8 to convert factored resistance value to ASD value.
<br /> 2 Linear interpolation between embedment depths and concrete compressive strengths is not permitted.
<br /> 3 Apply spacing,edge distance,and concrete thickness factors in tables 6 to 15 as necessary. Compare to the steel values in table 22.
<br /> The lesser of the values is to be used for the design.
<br /> 4 Tablular values are for normal-weight concrete only. For lightweight concrete multiply design strength by Ae as follows:
<br /> for sand-lightweight,A.=0.68;for all-lightweight,k =0.60
<br /> 5 Tabular values are for static loads only.Seismic design is not permitted for uncracked concrete.For seismic tension loads,multiply cracked concrete tabular val-
<br /> ues in tension by the following reduction factors:
<br /> 1/4-in diameter by 1-5/8-in nominal embedment depth-aN 3.,,=0.60 All other sizes-aN,5.!S=0.75
<br /> No reduction needed for seismic shear.See PTG Ed.19 Section 3.1.8 for additional information on seismic applications.
