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.
Hint: take advantage of symmetry to simplify the analysis by slope deflection.
