A rectangular portal frame of uniform section is hinged at the base and subjected to the loads shown in Figure S9.2 . The shape factor of the section is 1.15, the yield stress of the steel is 16 kips/in 2, and the required load factor is 1.75. Neglecting the effects of axial loads and instability, determine the required elastic section modulus of the members.
