Abstract
Une poutrelle supportant des membrures inférieures (20) comprend les éléments qui suivent. Une membrure inférieure allongée (24) formée à froid à partir d'une pièce unitaire de tôle d'acier. La membrure inférieure allongée comprend une partie de semelles et une partie recevant une âme dans le plan orthogonal. La partie recevant l'âme comporte deux pattes recevant la toile (46, 48) et une paire de semelles intérieures (45, 47) qui s'étendent vers l'extérieur à partir de l'une des pattes recevant l'âme, respectivement. La poutrelle comprend aussi une membrure supérieure allongée (22) de longueur généralement identique à la membrure inférieure, et une âme d'acier généralement plane (26) fixée à la partie recevant l'âme de la membrure inférieure allongée (24) entre les deux pattes recevant l'âme (46, 48) et fixées à la membrure supérieure allongée (22). De multiples poutrelles supportant des membrures inférieures peuvent constituer un système de support pour systèmes composites de planche et de toit.
