Sažetak
This work presents a beam element model for second-order analysis of spaced framed structures with thin-walled cross-sections. Applying the updated Lagrangian incremental formulation and non-linear displacement field of thin-walled cross-section, which accounts for restrained warping and includes second-order displacement terms due to large rotation effects, equilibrium equations of a straight beam element are firstly developed. Material non-linearity is introduced for an elastic-perfectly plastic material behavior through the plastic hinge formation at finite element ends. For this, a corresponding plastic reduction matrix is deter-mined. The interactions of element forces are taken into account.
