Kasprzak, Auteur Année de publication : 2011 Article en page(s) : pp. 886-896 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Thin-walled  beam  Global  and  local  buckling  Drop  flanges  Channel  beams Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : The subject of the paper is cold-formed thin-walled channel beams with open or closed profile of drop flanges. The geometric properties of two C-sections are described including warping functions and warping inertia moments. The analytical solutions of problems of global and local stability of thin-walled beams are presented. The theoretical solutions of elastic buckling problems of these beams are numerically found using FEM and are experimentally verified. The results of analytical and numerical investigations are compared and presented in the tables and figures.
