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 compresive strengths is not permitted . 3 Tabular value is for one anchor per flute . Minimum spacing along the length of the flute is 3 x h nom
( nominal embedment ).
4 Tabular values are lightweight concrete and no additional reduction factor is needed . 5 No additional reduction factors for spacing or edge distance need to be applied . 6 Comparison of the tabular values to the steel strength is not necessary . Tabular values control . 7 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete . 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 - α N , seis
= 0.60
All other sizes - α N , seis
= 0.75 . See PTG Ed . 21 Section 3.1.8 for additional information on seismic applications .
8 For the following anchor sizes , an additional factor for seismic shear must be applied to the cracked concrete tabular values for seismic conditions : 1 / 4-inch diameter - α v , seis
= 0.75
3 / 8-inch diameter - α v , seis = 0.60
1 / 2-inch diameter - α v , seis = 0.60
5 / 8-inch diameter - α v , seis = 0.60
3 / 4-inch diameter - α v , seis = 0.70
