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.

Bracing a member against sidesway means that its ends cannot translate with respect to each other.

Bracing a member against sidesway means that its ends can translate with respect to each other.

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:    W14x193, A992    680 kip axial compression    640 ft-kip bending moment    L = 18 ft    pin-pin connected    laterally braced at ends    Kx = Ky = 1

Determine Cb for the member if the moments at the top and bottom are 150 ft-kip and 450 ft-kip, respectively.

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 = 140 kip, Mnt = 100 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 = 1.057.

Using LRFD, 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 = 162.8 kip, Mnt = 266.4 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 = 1.023.
