Compute the ASD elastic critical buckling strength, Pe1, for the W14x74 made from ASTM A992 steel with L = 12 ft, P = 240 kip, M = 260 kip-ft, and Kx = Ky = 1.0. Bending is about the x axis. The member is part of a braced frame, and the given service loads are 50% dead load and 50% live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity was unreduced.
