Determine the reactions and draw the shear and bending moment diagrams for the three-span continuous beam shown in Fig. 13.21 (\mathrm{a}) due to the uniformly distributed load and due to the support settlements of 5 / 8 in. at B, 1 \frac{1}{2} in. at C, and 3 / 4 in. at D. Use the method of consistent deformations.
