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.
P10.10. A W27×94 section of A572 Grade 50 steel 34 feet long, it is used as a simply supported beam. It is subjected to a factored concentrated load of 90 kips at 12 feet from each support. In addition, the beam is subjected to a factored moment of 340 kips-ft at its left end (counterclockwise). Neglect the self-weight of the beam in the calculations, and check whether the beam is safe according to the LRFD. Lateral support is only provided at the ends and load points.
