Problem
A member in a braced frame supports an axial compressive load and end moments that cause bending about both axes of the member. A second-order analysis was performed with factored loads and reduced member stiffnesses to obtain the moments and axial force. Use LRFD and select the lightest W shape of A992 steel.
FIGURE P6.8-4
The beam-column in the figure below is a member of a braced frame. A second-order analysis was performed with factored loads and reduced member stiffnesses to obtain the moments and axial force shown. Use LRFDand determine whether this member is adequate. Suppose that P = 165 kFor W10 x 60 with L, = 15 ft and C6 = 1.0: ф,M, = 257 ft-kips, ф,M, = 280 ft-kips;for Lc = 15 ft: cPr = 556 kips.
The beam shown in Figure is a W16 x 31 of A992 steel. It supports a reinforced concrete floor slab that provides continuous lateral support of the compression flange. The service dead load is 450 /byft. This load is superimposed on the beam; it does not include the weight of the beam itself. The service live load is 550 lby/ft. Does this beam have adequate moment strength?
