1 See section 3.1.8 to convert factored resistance value to ASD value . 2 Linear interpolation between concrete compressive strengths is not permitted . 3 Tabular values are for single anchor located at edge distance ( c ) and spacing ( s ) greater than 24 ". For anchors with edge distance or spacing less than 24 " use CSA A23.3 to calculate load reduction factor . Compare the value to the steel values in Tables 6 and 9 . 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
= 0.85 ; for all-lightweight , λ a = 0.75 .
5 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete .
