Where does the maximum moment amplification occur for single-curvature bending?

Compute the LRFD elastic critical buckling strength, Pe1, for the W8x58 made from ASTM A992 steel with L = 15 ft, P = 490 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.

Compute the value of Cm for a beam-column with a moment of 240 kip-ft at the top and a moment of 490 kip-ft at the bottom.

Using ASD, determine the value of the AISC interaction equation for a W12x106 made from ASTM A992. Let L = 16 ft, Kx = Ky = 1.0, and Cb = 1.0. The factored loads are Pnt = 190 kip, Mnt = 120 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 = 1.044.

Compute the ASD elastic critical buckling strength, Pe1, for the W10x88 made from ASTM A992 steel with L = 15 ft, P = 230 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.

The length of chain between the top loop and the half hitch should alway be placed on the bottom side of the front leg during delivery.

Identify the correct stiffness reduction factor for the direct analysis method.

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.

Determine Cb for the member if the moments at the top and bottom are 100 ft-kip and 300 ft-kip, respectively.

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.
