Euler-Bernoulli Beam-Column

The beam-column member can be considered as combination of a beam and a truss member. Therefore,the local stiffness matrix of Euler-Bernoulli Beam in 2-dimensional space can be expressed as follows.

Note that this matrix formulation ignores transversal shear deformations. In order to account for shear deformation one can utilize Timoshenko Beam-Column element.
