Ja concrete slab is supported by the bar joists (spaced 3 ft apart) that rest on several steel frames. Each bar joist has a length of 25 ft and can be considered to be simply supported. The interior frame can be considered fix connected at Al and pin at C. B is a fixed joint. Assume the floor loading is 150 lb/ft2 and each bar joist has a weight of 500 lb. Determine all support reactions and the endmoments at A, B, and C. Draw the shear and moment diagram for the frame. El is constant. SG Joid Concrete ???m ? J 18
