A W14 x 90 of A992 steel (Fy= 350 MPa and Fu= 450 MPa) is used as a 4.25 m (14 ft) long beam-column with Kx= 0.9 and Ky= 1.0. The member is braced against sidesway, the ends are restrained, and there are transverse loads between the ends. The member is subjected to the following service loads and moments: an axial compressive load of 1520 KN and a bending moment of 335 KN.m about the strong axis. The composition of each is 35% dead load and 65% live load. Use Cb= 1.6 and consider moment amplification. Use LRFD
