摘要：This paper presents the results of numerical analysis conducted to investigate compressed thin-walled Z-profile weakened by holes with variable geometrical parameters. The specimens made of constructional steel were articulately supported on the edges of the cross-section in the upper and lower parts. The FEM analysis examined the nonlinear stability of these structures in the post-buckling state, where the mode of buckling was forced to ensure their stable behaviour. The numerical computations were performed within the geometrically nonlinear range until the yield point was reached. The investigation involved determining the effect of holes sizes on allowable operational loads. Numerical analysis was conducted with the Abaqus commercial FEM software package.
