What is Trusses and Frames in FEM Analysis about?

Trusses are structures made of straight bars joined at nodes, where forces are considered to act. Frames have rigidly connected members that experience various internal forces. A 2D truss element is analyzed, relating nodal displacements in local and global frames. The strain energy of an element is defined using its stiffness matrix in the global frame. As an example, the displacement of node 4 is found for a simple 2D truss under a horizontal force, by solving the system of finite element equations relati
