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.
