NOTE
1 . Loads are based on ICC ELC-5019 and CSA S136-16 . 2 . Strength Reduction factors for flexure and compression are 0.90 and 0.80 , respectively . 3 . Maximum factored beam loads in table are given in total uniform load . ( W * Span ) and based on a uniformly loaded condition with simply supported ends . For other loading and support conditions , see Table 6 for applicable load and deflection modification factors .
4 . Beams spans in table are assumed to be sufficiently laterally braced . Unbraced spans may reduce beam load carrying capacity . See Table 37 for reduction factors for unbraced conditions .
5 . Profile weight , 1.96 lbs / ft ( 2.91 kg / m ), must be deducted from maximum factored beam load values . 6 . C . G . is the ‘ Center of Gravity ’ of the cross section . 7 . ** indicates KL / r for compression exceeds 200 . 8 . Maximum factored load at channel face assumes K value of 0.8 .
