Solve by Stiffness Matrix Method, consider all bars as axially rigid

(\frac{E A}{L},

so that axial deformation is neglected. Keep in mind the lateral displacements are the same for the horizontal bar due to be axially rigid, also

,

vertical displacement is zero for node A

,

but not for B because the bar is inclined. I know this because the frame was modeled in a software before. Do not skip any hand calculations, thanks in advance.

E =
