Question

Element stiffness matrix for truss element, beam element and torsional element

Answer 1

A beam element has three translational and three rotational degrees of freedom at each node with respect to the ECS. The axial stiffnessof a beam element is identical to the axial stiffness of a truss element. In the same way as the axial stiffness thetorsional stiffness of the beam element can be calculated.
