Abstract
An assumed-stress hybrid 2-node beam element is formulated using the Hellinger-Reissner variational principle. Independent approximations are made for the stresses and displacements. The stress field is assumed to be consistent with the force and moment equilibrium equations. The displacement field is assumed to be linear except that the transverse deflections vary quadratically using the rotational freedoms, The element is implemented in COMET and coupled with its corotational utilities. This enables an analyst to extend the element to problems involving geometric nonlinearities. Excellent performance of the element for nonlinear behaviors of both a stiffening and softening behavior is demonstrated.
