The beam-column of A992 steel is part of a braced frame with L = 15 ft, Pu = 300 kip, Mux = 150 kip-ft. A second-order analysis was performed with factored loads and reduced member stiffnesses to obtain the moments and axial force. Bending is about the strong axis. Considering only the following shapes and values obtained from the AISC procedure for ASD, select the lightest acceptable shape. Let Kx = 1.0, Ky = 1.0, and Cb = 1.0.ShapeValue of AISC interaction equationW12x581.554W12x721.138W12x791.032W12x870.929W12x960.835
