1 See section 3.1.8 to convert factored resistance 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 23 to 25 as necessary . Compare to the steel values in table 34 . The lesser of the values is to be used for the design .
4 Tablular values are for normal-weight concrete only . For lightweight concrete multiply design strength by λ a as follows : for sand-lightweight , λ a = 0.68 ; for all-lightweight , λ a
= 0.60 5 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete .

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 value is for 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 .
