Notes :
1 . Loads are based on ICC-ES ELC-5019 and CSA S136-16 , the North American Specification for the Design of Cold-Formed Steel Structural Members ( using the Appendix B provisions applicable to Canada ), CSA Group .
2 . Resistance 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 page 32 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 page 49 for reduction factors for unbraced conditions .
5 . Profile weight , 4.43 lbs / ft ( 64.67 N / 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 girder face assumes K value of 0.8 .
