Notes:
1. Loads are based on CSA S136-16, the North American Specification for the
Design of Cold-Formed Steel Structural Members. 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 36 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 68 for reduction factors for unbraced conditions.
5. Profile weight, 2.63 lbs / ft( 38.39 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 allowable load at girder face assumes K value of 0.8.
