1 See section 3.1.8 to convert design strength value to ASD value .
3,325 ( 14.8 )
3,700 ( 16.5 )
2 Linear interpolation between embedment depths and concrete compressive strengths is not permitted .
3,700 ( 16.5 )
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 to steel values in table 4 is not required . Values in tables 26 control . 7 Comparison to steel values in table 12 is not required . Values in tables 27 control . 8 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete .
