Cоmpute the ASD mоment аmplificаtiоn fаctor B1 for the W8x58 made from ASTM A992 steel with L = 12 ft, P = 260 kip, M = 240 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 using the requirements for the approximate second-order analysis method meaning that a reduced stiffness was used.
