Compute the value of Cm for a beam-column with a moment of 570 kip-ft at the top and a moment of 130 kip-ft at the bottom.

Compute the LRFD moment amplification factor B1 for the W18x65 made from ASTM A992 steel with L = 15 ft, P = 220 kip, M = 230 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.

Compute the LRFD moment amplification factor B1 for the W18x65 made from ASTM A992 steel with L = 14 ft, P = 300 kip, M = 210 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.

Stranger wariness generally begins to appear in infants at around:

Compute the ASD moment amplification factor B1 for the W14x74 made from ASTM A992 steel with L = 15 ft, P = 200 kip, M = 230 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.

Determine Cb for the member if the moments at the top and bottom are 270 ft-kip and 340 ft-kip, respectively.

What is the average life expectancy for a patient that suffers from Hutchinson-Gilford Progeria Syndrome (HGPS)?

Compute the ASD moment amplification factor B1 for the W10x88 made from ASTM A992 steel with L = 16 ft, P = 200 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 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.
