A load bearing deck (20) of a modular structural section (30) for use in a support structure such as a load bearing deck or highway bridge. The at least one modular structural section (30) includes at least one beam (50) and a load bearing deck (20) preferably formed of a polymer having elongate core members (46) having a polygonal shape, preferably a trapezoidal shape. Alternatively, the load bearing deck comprising at least one sandwich panel (30) is suitable for applications such as barge decks, hatchcovers, and other load bearing wall applications. Methods of constructing a support structure utilizing the modular structural section (30) including the polygonal, preferably trapezoidal core deck, and support members (22) are also provided.
L'invention a trait à un tablier porteur (20), inclus dans une section structurelle modulaire (30), utilisable dans une structure de support telle qu'un tablier porteur ou un pont-route de type autoroute. Cette section structurelle modulaire (30), une du moins, comporte au moins une poutre porteuse 50) et un tablier porteur (20), à base, de préférence, d'un polymère ayant des éléments allongés d'âme (46), de forme polygonale, trapézoïdale, de préférence. Selon une variante, le tablier porteur, comportant au moins un panneau sandwich (30) se prête à des applications du genre plateaux de barge, panneaux de cale, et autres parois de partage de charges. L'invention concerne également des procédés de construction de structure de support utilisant ladite section structurelle modulaire (30), incluant le panneau - âme polygonal, trapézoïdal, de préférence, ainsi que des éléments de soutien (22).
