Compute the ASD moment amplification factor B1 for the W8x58 made from ASTM A992 steel with L = 14 ft, P = 230 kip, M = 210 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.

Compute the ASD moment amplification factor B1 for the W12x106 made from ASTM A992 steel with L = 16 ft, P = 260 kip, M = 270 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 30% dead load and 70% live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity was unreduced.
