NOTE
1 . Loads are based on ICC-ES ESR-5019 and AISI S100-16 . 2 . 3 .
Safety Factors for flexure and compression are 1.67 and 1.80 , respectively . 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 Table 6 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 Table 37 for reduction factors for unbraced conditions . 5 . Profile weight , 3.01 lbs ./ ft ( 4.48 kg / 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 that max Allowable Load is limited due to Shear Flow capacity . Max allowable shear load in the beam due to shear flow capacity is 1,347 lbs . 9 . ** Indicates KL / r for compression exceeds 200 . Maximum allowable load at channel face assumes K value of 0.8 . 10 . For Channel Separation capacity please contact HILTI .
