The object of the study was a short profile with a C-shaped section, made of a carbonepoxy composite. The column is a structure consisting of thin-walled flat plates joined on longer edges. The analysed C-section was subjected to eccentric pressure shifted from the cross-section centre of mass. The boundary conditions assumed for the study ensured the appropriate support of the end sections of the profile. The conducted analysis allowed for the evaluation of the effects of eccentricity on the value of the critical force of the structure. The scope of the study included both experimental research conducted on a physical model of the structure and numerical analysis by the finite element method using Abaqus software. The conducted numerical analysis included the solution of the eigenvalue problem of structure’s stability. On the basis of the example analysed below, it was possible to determine the effect of the eccentricity of load on the behaviour of the thin-walled composite column.
