The compound beam below consists of beam AC pin-connected to beam CB using plates bolted on each side of the beam webs. There is a roller-support at A and a fixed support at B. Beam AC is subject to a live distributed load wL = 2 k/ft and a live concentrated load of PL = 16 kip, while beam CB is subject to a superimposed dead load of 3 k/ft. Lateral support is provided at A, C, and B. Do the following: 1. Assuming A992 steel, select the lightest W-shape for beam AC. Ignore self-weight and neglect deflection. Show all work to receive full credit. 2. Assuming A325 bolts will be used in the connection at C, select the minimum bolt diameter based on shear only. Show all work to receive full credit. 16 k 2 k/ft 3 k/ft 000 00 o 000 00O B А C -12 ft- - 4 ft -12 ft-
