Title
(EN) STRUCTURAL DESIGN PRINCIPLES FOR DIAGONAL BRACINGS IN TRUSS AND BEAM SUPPORT SYSTEMS
(FR) PRINCIPES DE CONCEPTION STRUCTURELLE POUR ENTRETOISES DIAGONALES DANS DES SYSTÈMES DE SUPPORT DE POUTRE ET DE FERME
Abstract
(EN)
A structural lattice includes a rectangular base defined by four periphery beams, and two non-diagonal beams that divide the rectangular base in four quadrants. The structural lattice further includes a diagonal reinforcement strut system overlaid on the rectangular base and having at least two intersecting sets of diagonal beams forming an open-and-closed cell architecture.

Dans la présente invention, un treillis structurel comprend une base rectangulaire définie par quatre poutres périphériques, et deux poutres non diagonaux qui divisent la base rectangulaire en quatre quadrants. Le treillis structurel comprend en outre un système d'entretoise de renforcement diagonal superposé sur la base rectangulaire et ayant au moins deux ensembles d'intersection de poutres diagonales formant une architecture cellulaire ouverte et fermée
