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:    W14x109, A992    380 kip axial compression    380 ft-kip bending moment    L = 15 ft    pin-pin connected    laterally braced at ends    Kx = Ky = 1

An unbraced rigid frame depends on the transfer of moments at its joints for stability.

Compute the ASD moment amplification factor B1 for the W8x58 made from ASTM A992 steel with L = 12 ft, P = 260 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.

The web members of roof trusses are sometimes considered beam-columns.

Which of the following corresponds to the variable B2?

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

Determine Cb for the member if the moments at the top and bottom are 180 ft-kip and 330 ft-kip, respectively.

Compute the value of Cm for a beam-column in reverse-curvature bending with a moment of 180 kip-ft on one end and a moment of 570 kip-ft on the other end.

A member subjected to a counter-clockwise moment on both ends will experience _______.

Compute the ASD elastic critical buckling strength, Pe1, for the W10x88 made from ASTM A992 steel with L = 12 ft, P = 300 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.
