Problem 5 A 60 ft long beam in an industrial facility is subjected to a heavy gravity load and large lateral load as shown. Because of the length of the beam and the heavy loads, two eccentric diagonal braces AC and FD were added as shown to minimize beam bending and reduce its depth. From analysis, the LRFD Pu loads on braces AC and FD were 92 k (tension) and 154 k (compression) respectively. Brace FD was designed as W12x53. Verify that the W12x53 section for brace FD is adequate. Now that the section is verified to be adequate, is it the lightest section?. Braces AC and FD are pinned-pinned members (Kx = Ky = 1.0)

Problem 5
A 60 ft long beam in an industrial facility is subjected to a heavy gravity load and large lateral
load as shown. Because of the length of the beam and the heavy loads, two eccentric diagonal
braces AC and FD were added as shown to minimize beam bending and reduce its depth. From
analysis, the LRFD Pu loads on braces AC and FD were 92 k (tension) and 154 k (compression)
respectively. Brace FD was designed as W12x53. Verify that the W12x53 section for brace FD is
adequate. Now that the section is verified to be adequate, is it the lightest section?. Braces AC
and FD are pinned-pinned members (Kx = Ky = 1.0)
