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 14 to 19 as necessary . Compare to the steel values in table 31 . 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 .
