Use Fy = 50 ksi and select the lightest W12-shape for the beam–column shown in Figure P6.8-1. The member is part of a braced frame, and the axial load and bending moment are based on service loads consisting of 30% dead load and 70% live load (the end shears are not shown). Bending is about the strong axis, and Kx = Ky = 1.0. The frame analysis was performed consistent with the effective length method, so the flexural rigidity, EI, was unreduced.
a. Use LRFD.
b. Use ASD.
