Title (EN) HIGH STRENGTH STRUCTURAL MEMBERS
(FR) ELEMENTS DE CONSTRUCTION A RESISTANCE ELEVEE
Abstract:
(EN) A structural member (1) is thin walled and hollow. The walls (4, 5, 6, 7) of the member (1) have a series of protrusions (2) or depressions (3) formed in the general plane of each wall (4, 5) which act to strengthen the member (1). The depressions (3) in one wall (4, 5) abut the inner surface of an opposing wall (6, 7) to provide a resistance to crushing of the member (1). The position and alignment of the protusions (2) and depressions (3) can be altered to suit the intended use of the structural member (1). Structural members may be lintels, I-beams or of other structural shape and will have a lower mass when compared to members of the same strength.
(FR) Elément de construction (1) creux et à paroi mince. Les parois (4, 5, 6, 7) de l'élément (1) possèdent une série de protubérances (2) et de creux (3) formées dans le plan général de chaque paroi (4, 5) servant de renforcement à l'élément (1). Les creux (3) situés dans une paroi (4, 5) s'appuient contre la surface interne d'une paroi opposée (6, 7) afin de produire une résistance à l'applatissement de l'élément (1). La position et l'alignement des protubérances (2) et des creux (3) peuvent être modifiés pour être adaptés à l'utilisation proposée de l'élément de construction (1). Les éléments de construction peuvent être des linteaux, des poutrelles en I ou des éléments d'une autre forme et ils auront une masse inférieure en comparaison à des éléments de même résistance.
