a member in a braced frame supports an axial compressive load and end moments that cause bending about both axes of member. A second order analysis was performed with factored loads and and reduced members stiffnesses to obtain the moments and axial forces. USE LRFD and selet the lightest W shape of A992 steel? Axial=140 k. Mux= 150 ft-kips. Muy=150 ft-kips.
Mux=75 ft-kips. Muy=75 ft-kips.
