<br /> 1 See PTG Ed.19 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 6 through 15 as necessary.Compare to the steel values in Table 4.
<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,Aa=0.68.For all-lightweight,Aa=0.60.
<br /> 5 Tabular values are for static loads only. For seismic tension loads,multiply cracked concrete tabular values in tension by the following reduction factors:
<br /> 1/4-in diameter by 1-5/8-in nominal embedment depth-aN,sels=0.60
<br /> All other sizes-aN =0.75
<br /> No reduction needed for seismic shear. See PTG Ed.19 Section 3.1.8 for additional information on seismic applications.
