A direct 1D model able to describe the mechanical behaviour of thin-walled beams is used to analyse the initial postbuckling of some sample frames. The model allows to take into account the boundary conditions on warping in a very simple way and proves to be a very efficient tool for the analysis of thin-walled frames. Making use of the FEM based COMSOL multiphysics software, numerical results for a number of L frames are obtained and shown.

Abstract
A direct 1D model able to describe the mechanical behaviour of thin-walled beams is used to analyse the initial postbuckling of some sample frames. The model allows to take into account the boundary conditions on warping in a very simple way and proves to be a very efficient tool for the analysis of thin-walled frames. Making use of the FEM based COMSOL multiphysics software, numerical results for a number of L frames are obtained and shown.File in questo prodotto:
