IMPORTANT: MUST SOLVE BY USING the zero boundary condition at join D$,$ you can use fixed$-$roller end forces for member CD and remove the unknown joint displacement D$4.$ With DKI $=3$ and unknown joint displacements D$1,$ D$2,$ and D$3.$ You need to show complete steps and compatibility states.

The continuous beam shown below has a distributed load applied over span $BC$ and a

point load applied at joint $D.$ The steel beam $(E=29000$ksi$)$ has second moment of area

$I=900inc{h}^4.$ The beam has DKI$=4$ with unknown joint displacements shown in the figure.

UNKNOWN JOINT DISPLACEMENTS $(DKI=4)$

Use the table of end moments and end shears for fixed$-$fixed beams in order to form the

following objects by direct assembly.
