In order to provide the required load resistance at the guard,the post must not only be fastened • to the rim joist,but also tied back into the joist framing. Machine bolts through the post and rim joist alone do not typically meet the performance requirements of the code.The details on pp.29-32 have been shown through testing or analysis to resist the required 200 lb.concentrated load(or load of 50 lb. per linear foot per IBC)applied in an outward direction for maximum guard heights of 36"and 42"above the deck surface.
