The Beam Element,he beam element has modulus of elasticity ., moment of inertia ., and length .. Each beam element has two nodes and is assumed to be horizontal as shown in Figure 7.1. In this case the element stiffness matrix is given by the following matrix, assuming axial deformation is neglected (see reference ).
