Determine Cb for the member if the moments at the top and bottom are 240 ft-kip and 520 ft-kip, respectively.

Ordinary structural analysis methods that do not take the displaced geometry into account are called _______ methods.

Using ASD, determine the value of the AISC interaction equation for a W18x65 made from ASTM A992. Let L = 16 ft, Kx = Ky = 1.0, and Cb = 1.0. The factored loads are Pnt = 120 kip, Mnt = 150 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 = 1.024.

Compute the LRFD elastic critical buckling strength, Pe1, for the W14x74 made from ASTM A992 steel with L = 15 ft, P = 260 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 40% dead load and 60% live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity was unreduced.

The beam-column of A992 steel is part of a braced frame with L = 15 ft, Pu = 300 kip, Mux = 150 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 the following shapes and values obtained from the AISC procedure for ASD, select the lightest acceptable shape. Let Kx = 1.0, Ky = 1.0, and Cb = 1.0.ShapeValue of AISC interaction equationW12x581.554W12x721.138W12x791.032W12x870.929W12x960.835 

Determine Cb for the member if the moments at the top and bottom are 150 ft-kip and 530 ft-kip, respectively.

Compute the value of Cm for a beam-column in reverse-curvature bending with a moment of 160 kip-ft on one end and a moment of 560 kip-ft on the other end.

Which of these is actually easier when pulling a calf?

Compute the LRFD elastic critical buckling strength, Pe1, for the W10x88 made from ASTM A992 steel with L = 16 ft, P = 500 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 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.

Interaction formulas can involve more than one type of resistance.
