Analyze the right-angle frame shown below by the Direct Stiffness Method (not theunit displacement based method). E = 200 GPa, I = 1.33×10-3 m4, and A = 0.04 m2. Theflexural rigidity EI and the axial rigidity EA are constant throughout the frame. Assemblethe global stiffness matrix for the frame by appropriately combining the stiffness matricesfor the frame elements, applying boundary conditions, and solving for the horizontal andvertical displacements and rotation at point B. Do NOT neglect axial deformations. Showall work
