A beam model for nonlinear stability analysis of beam-type structures with flexible connections
This work presents a large-displacement beam model for the nonlinear stability analysis of beam-type structures, composed of the straight and prismatic beam members, with flexible connections. The equations of equilibrium are derived using the virtual work principle and the updated Lagrangian incremental (UL) description. Displacements are allowed to be large, but strains are assumed to stay small. External loads are static and conservative. Internal moments are represented as the stress resultants calculated by the Euler- Bernoulli-Navier theory for bending and the Timoshenko-Vlasov theory for torsion. The external stiffness approach (ESA) is used in the force recovering. With this approach, the external stiffness matrix of a beam element is included in the force recovering to exclude the rigid-body effects.
