Notes:
1. Loads are based on 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 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 67 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 allowable load at channel face assumes K value of 0.8.
