1. Analyze the Vierendeel truss in Figure P11.31 by moment distribution. Draw the shear and moment curves for members AB and AF. Sketch the deflected shape, and determine the deflection at midspan. Given: EI is constant, E = 200 GPa, and I = 250 × 106 mm4.

2. Analyze the frame in Figure P11.32 by moment distribution. Draw the shear and moment curves. Compute the horizontal deflection of joint B. Sketch the deflected shape. E is constant and equals 30,000 kips/in.2
