..The horizontal reactions at A, B, and C are 40 kN, 80 kN, and 40 kN,
respectively, all directed to the left. Calculate column moments, girder shears and
moments and girder and column axial forces by dividing the frame into independent
portals. Then draw the shear and moment diagrams of all girders and columns.
