Using ASD, determine the value of the AISC interaction equation for a W8x58 made from ASTM A992. Let L = 16 ft, Kx = Ky = 1.0, and Cb = 1.0. The factored loads are Pnt = 170 kip, Mnt = 170 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 = 1.238.

In a column subjected to only axial load, a bending moment will develop if the axial load is applied through the centroid of the cross section.

Determine Cb for the member if the moments at the top and bottom are 250 ft-kip and 450 ft-kip, respectively.

Compute the value of Cm for a beam-column with a moment of 180 kip-ft at the top and a moment of 510 kip-ft at the bottom.

If you do not have lube available to help with the delivery of a calf, which two of these can be used in its place?

The beam-column of A992 steel is part of a braced frame with L = 15 ft, Pu = 280 kip, Mux = 130 kip-ft. A second-order analysis was performed with factored loads and reduced member stiffnesses to obtain the moments and axial force. Bending is about the strong axis. Considering only W14x68, W14x74, and W14x82, use ASD to select the lightest acceptable shape. Let Kx = 1.0, Ky = 1.0, and Cb = 1.0.

Compute the LRFD moment amplification factor B1 for the W12x106 made from ASTM A992 steel with L = 16 ft, P = 280 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 using the requirements for the approximate second-order analysis method meaning that a reduced stiffness was used.

A braced rigid frame depends on the transfer of moments at its joints for stability.

For the beam-column depicted in the following image, the ratio of M1/M2 is _______.

Compute the LRFD elastic critical buckling strength, Pe1, for the W10x88 made from ASTM A992 steel with L = 13 ft, P = 300 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 50% dead load and 50% live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity was unreduced.
