Abstract

The paper is devoted to a thin-walled rectangular frame. The frame is simply supported in the planes of symmetry and in-plane compression forces are applied in the corners. The longitudinal and transverse thin-walled beams of the frame are rigidly joint at the corners. Two buckling forms of the frame are studied. The analytical and numerical-FEM (SolidWorks) models are formulated. The results of the studies are presented in Tables and Figures.
