Compute the LRFD moment amplification factor B1 for the W18x65 made from ASTM A992 steel with L = 14 ft, P = 260 kip, M = 280 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 using the requirements for the approximate second-order analysis method meaning that a reduced stiffness was used.

Compute the ASD elastic critical buckling strength, Pe1, for the W10x88 made from ASTM A992 steel with L = 12 ft, P = 300 kip, M = 200 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.

Using ASD, determine whether the following member satisfies the appropriate AISC interaction equation. Do not consider moment amplification. The loads are 50% dead and 50% live load. Bending is about the x-axis.Given:    W14x82, A992    Applied axial compression force = 120 kip    Applied constant bending moment = 240 ft-kip    L = 13 ft    pin-pin connected    laterally braced at ends    Kx = Ky = 1    Cb = 1
