Compute the LRFD elastic critical buckling strength, Pe1, for the W14x74 made from ASTM A992 steel with L = 12 ft, P = 480 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 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.

Using LRFD, determine the value of the AISC interaction equation for a W16x57 made from ASTM A992. Let L = 16 ft, Kx = Ky = 1.0, and Cb = 1.0. The factored loads are Pnt = 236.8 kip, Mnt = 192.4 kip-ft, The member is part of a braced frame, bending is about the x axis, and the LRFD moment amplification factor has been determined to be B1 = 1.053.

Using ASD, determine the value of the AISC interaction equation for a W10x88 made from ASTM A992. Let L = 16 ft, Kx = Ky = 1.0, and Cb = 1.0. The factored loads are Pnt = 180 kip, Mnt = 180 kip-ft, The member is part of a braced frame, bending is about the x axis, and the ASD moment amplification factor has been determined to be B1 = 1.095.

Compute the ASD elastic critical buckling strength, Pe1, for the W8x58 made from ASTM A992 steel with L = 13 ft, P = 250 kip, M = 220 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.
