<br /> 1 See section 3.1.8 to convert design strength 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 5 to 6 as necessary. Compare to the steel values in table 9.
<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 A.as follows:
<br /> for sand-lightweight,A.=0.68;for all-lightweight,Aa =0.60
<br /> 5 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-in diameter by 1-5/8-in nominal embedment depth-aN5e1S=0.60
<br /> 1/4-in diameter by 2-1/2-in nominal embedment depth-aN5e1S=0.75.
<br /> No reduction needed for seismic shear.See section 3.1.8 for additional information on seismic applications.
