1 See 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 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 . For seismic tenison loads , multiply cracked concrete tabular values in tension by α N , seis
= 0.75 .
8 For seismic shear , an additional factor must be applied to the cracked concrete tabular values for seismic conditions : 1 / 4-in diameter by 1-5 / 8-in nominal embedment depth - α V , seis
= 0.44
1 / 4-in diameter by 2-1 / 2-in nominal embedment depth - α V , seis
= 0.85 See Section 3.1.8 for additional information on seismic applications .
