For the shown space frame and by using the matrix stiffness method, determine:

$1-$ Joint displacements.

$2-$ Member local end forces.

$3-$ Support reactions.

$4-$ Draw B$.$M$.$D for the frame.

$5-$ Compare your results against any available software $($This part is Optional$).$

Show Full Details of all of your calculations $($Failing in doing so will cost you

losing the credit of the question$)$
