A properly restrained frame shown in the figure below has a hinged support at joint A and fixed

supports at points D and C$.$ Evaluate and analyze the following:

Part $1$: Magnitude of the bending moment at points $C$ and $D$ and joints A and $B$ using $8$

cycles of moment distribution method.

$(25$ Marks$)$

Part $2$: Plot the shear and moment diagram of the frame.
