See attachment for question and diagrams.

This problem is concerned with using the stiffness matrix method to find displacements and force in a structure. My problem is pre-eliminating the members. i have attached 2 diagrams. i would like help in trying to get from the first diagram, to the second diagram ( with eliminated members and forces calculated)

I know that

∑Fx=0

∑Fy=0

∑M=0

However, the UDL and other factors are causing me problems.

I don’t know where to start with this

Thanks
