considering moment amplification factor B1 if the
service axial compressive load and bending moment in the
beam-column are replaced by 302kips and 241kip-foot respectively.
Use Fy=50ksi, E=29000ksi, Ix=1110in4 , ФPn=1130kips,
ФMn=646kip-foot.
From formula Mux = B1x+Mnt, I got 368.29, but it's wrong
A W14 x 99 of A992 steel is used as a 14-foot-long beam-column with K, = 0.9 and K, = 1.0. (An analysis was performed consistent with the effective length method; therefore, the flexural rigidity, El, was unreduced.) The member is braced against
sidesway, and there are transverse loads between the ends. The member is subjected to the following service loads and moments: an axial compressive load of 340 kips and a bending moment of 250 ft-kips about the strong axis. The composition of each is 33% dead load and 67% live load. Use Cb = 1.6
