Sažetak
This paper presents a beam formulation for large displacement analysis of framed structures with semi-rigid connections. Within the framework of updated Lagrangian incremental formulation, the equilibrium equations of an elastic beam element are firstly developed. Material nonlinearity is introduced for an elastic-perfectly plastic material through the plastic hinge formation at finite element ends. To account for the semi-rigid connection behaviour, a special transformation procedure is developed. The numerical algorithm is implemented in a computer program and its reliability is validated trough an example.
