CA 2717203

A profiled deck is roll-formed from a steel sheet to define at least one pair of crests, a stiffener upstanding from the surface of each crest, a trough positioned between the or each pair of crests, and inclined webs extending between the sides of the trough and the neighbouring sides of the crests. The boundary between each web and crest defines a corner which has a smooth curvilinear profile and the elemental compression width of each crest is no more than four times the elemental compression width of the respective stiffener. Furthermore, the radius of each curvilinear corner is not less than 33mm.

L'invention concerne un tablier profilé laminé à partir d'une tôle d'acier pour définir au moins une paire de crêtes, un raidisseur se dressant depuis la surface de chaque crête, un creux situé entre la ou chaque paire de crêtes, et des parois inclinées s'étendant entre les côtés du creux et les côtés contigus des crêtes. La limite entre chaque paroi et crête définit un angle qui a un profil curvilinéaire lisse et la largeur de compression élémentaire de chaque crête ne fait pas plus de quatre fois la largeur de compression élémentaire du raidisseur respectif. Par ailleurs, le rayon de chaque angle curvilinéaire ne fait pas moins de 33 mm.
