The frame shown below has a span of 12 m with 4 m high columns. It has a pitched roof of a height h = 2.5 m. Supports A and C are pin supports and B is a pin. Draw the free body diagram of this frame. Then calculate the reactions and draw the shear force and bending moment diagrams of the frame. Repeat the above steps assuming h = 0, 3, 6, 9, and 12 m. Determine the optimum h values to give you (a) the smallest shear force at the top of the columns and (b) the smallest bending moment at the top of the columns. Comment on the results. Repeat the analyses using any analysis computer program. 6 kN/m 6 kN/m B h = 2.5 m 2 kN/m 4 m 6 m 6 m
