Sažetak
This work presents a one-dimensional finite element formulation for buckling analysis of flexibly connected thin-walled frames. Equilibrium equations of a 14-d.o.f. beam element are derived by applying linearized virtual work principle and introducing the nonlinear displacement field of asymmetric thin-walled cross-sections, which accounts for restrained warping as well as second-order displacement terms due to large rotations. The influence of connections behaviour is introduced in the numerical model by transforming stiffness matrices of a conventional beam element and for this purpose a special transformation matrix is derived.
