Compute the LRFD elastic critical buckling strength, Pe1, for the W14x74 made from ASTM A992 steel with L = 15 ft, P = 480 kip, M = 230 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 40% dead load and 60% live load. The frame analysis was performed using the requirements for the approximate second-order analysis method meaning that a reduced stiffness was used.
