The beаm-cоlumn оf A992 steel is pаrt оf а braced frame with L = 15 ft, Pu = 350 kip, Mux = 115 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 LRFD, select the lightest acceptable shape. Let Kx = 1.0, Ky = 1.0, and Cb = 1.0.ShapeValue of AISC interaction equationW12x581.020W12x720.744W12x790.675W12x870.608W12x960.547
