Notes : 1 . Loads are based on ICC-ES ESR-5019 and AISI S100-16 , the North American
Specification for the Design of Cold-Formed Steel Structural Members . 2 . Safety factors for flexure and compression are 1.67 and 1.80 , respectively . 3 . Allowable 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 , 1.1 lbs / ft ( 16.09 N / m ), must be deducted from allowable beam load values .
6 . Multiply tabulated load values by 1.5 to obtain Load and Resistance Factor
Design ( LRFD ) values . 7 . C . G . is the ‘ Center of Gravity ’ of the cross section . 8 . ** indicates KL / r for compression exceeds 200 . 9 . Maximum allowable load at channel face assumes K value of 0.8 .
