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.
