The specimen study consists of short, thin-walled columns made of cold-formed steel with an open top-hat cross-section. The walls in the specimens analyzed are made up of thin sheet component. Profiles were analyzed to classify the critical forces and post-critical stability paths. The ends of the column profile are considered to be supported. The numerical investigation was undertaken using the finite element method. The research includes an investigation of the post-critical stage of the profile on the different gravity loads of different thicknesses, depending on the eigenvalues of the profiles. The numerical simulation of the profiles is done using the ABAQUS® software. Based on a comparison of the outcomes of the profiles, an optimal profile is recommended for further analysis.
