A W21 x 68 is used as a simply supported beam with a span length of 12 feet. Lateral support of the compression flange is provided only at the ends. Loads act through the shear center, producing moments about the x and y axes. The service load mo- ments about the x axis are MDx = 48 ft-kips and M = 144 ft-kips. Service load moments about the y axis are MDy = 6 ft-kips and My = 18 ft-kips. If A992 steel is used, does this beam satisfy the provisions of the AISC Specification? Assume that all moments are uniform over the length of the beam. %3D
