PROFIL PORTEUR COMPOSE, CINTRE, POUR STRUCTURES LEGERES, RESULTANT DE L'ASSEMBLAGE DE TROIS PROFILS ELEMENTAIRES SOLIDARISES ENTRE EUX

摘要

The load bearing structure is formed by the superpositioning and assembling of three elementary sections. A self-stacking base section (1) which receives stiffeners and bottom structure fixed fastening panels. An upper section (2) serves to cap the structure cover plates and create the upper inertia of the composite section. A lower section (3) creates the bottom inertia of the composite structure.
