$2$ Deflection methods. An excavated hole is supported by the brace mechanism shown in

Figure $2.$ The hole is $6m$ deep and spans $16$ meters. The horizontal brace member has

pinned connections to steel plates on either side of the hole. The vertical member is

rigidly connected at the base. The vertical and horizontal members are rigidly

connected. EI is constant. The horizontal member supports a uniformly distributed load

of $8k\frac{N}{m}$ that spans from halfway between A and $B$ to $C.$ Fixed end moment equations

are given in Figure $3.(20$ pts$).$

A Analysis: Using the slope deflection method, determine the internal moments and

shears at joint $A,B,C,$ and $D.$

AND

B Draw the shear and bending moment diagrams for this frame.
