1 See PTG Ed . 21 Section 3.1.8 to convert design strength value to ASD value . 2 Linear interpolation between embedment depths and concrete compressive strengths is not permitted . 3 Apply spacing , edge distance , and concrete thickness factors in Tables 6 through 15 as necessary . Compare to the steel values in Table 4 .
The lesser of the values is to be used for the design . 4 Tabular values are for normal weight concrete only . For lightweight concrete multiply design strength by λa as follows :
For sand-lightweight , λa = 0.68 . For all-lightweight , λa = 0.60 . 5 Tabular values are for static loads only . For seismic tension loads , multiply cracked concrete tabular values in tension by the following reduction factors :
1 / 4-in diameter by 1-5 / 8-in nominal embedment depth - a N , seis = 0.60
All other sizes - a N , seis
= 0.75 No reduction needed for seismic shear . See PTG Ed . 21 Section 3.1.8 for additional information on seismic applications . ƒ ' c
