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 ef
( effective 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 only by α N , seis
=
0.75 , except for 3 / 4 x 4-3 / 4 h ef where α N , seis
= 0.73 . See Section 3.1.8 for additional information on seismic applications . 8 Minimum concrete thickness over the upper flute when anchor is installed in the lower flute . See Figure 4 and 5 . 9 For core drilled installations of 3 / 4 “ anchors installed at 4-1 / 2 “ nominal embedment , apply a reduction factor of 0.89 to the design tension strength of anchors installed in uncracked concrete .
