In Problem, take advantage of symmetry to simplify the analysis by slope deflection.

Figure P10.13 shows the forces exerted by the soil pressure on a typical 1-ft length of a concrete tunnel as well as the design load acting on the top slab. Assume that a fixed-end condition at the bottom of the walls at A and D is produced by the connection to the foundation mat. Determine the member end moments and draw the shear and moment curves. Also draw the deflected shape. EI is constant.
