Abstract

In the present numerical study, the critical load values that produce local buckling of thin and open section profiles when subjected to flexo-compression loads are determined and compared. For this, 2 calculation methods are used, these being the classic analytical method, the direct force method and the finite element method. Variants of an omega type cross section are adopted considering different sheet metal thicknesses and different dimensions of wings and flanges. The homogeneity of the profile material has also been taken into account.
