The member shown is a W12x79 of A572 Grade 50 steel and is part of a braced frame. The end moments are service load moments, and bending is about the strong axis. The end shears are not shown. The frame analysis was performed consistent with the effective length method, so the flexural rigidity, EI, was unreduced. If the end moments and axial load are 33% dead load and 67% live load, what is the maximum axial service load, P, that can be applied? Use Kx = Ky=1.0. Use LRFD. Answer: 309 kips T 15' 150 ft-k 150 ft-k
