Abstract

L'invention concerne un élément de structure (1) comportant : - un corps allongé (10), - au moins un tendeur (20) qui comprime longitudinalement le corps allongé, et - un moyen de désactivation (30) dudit tendeur, qui permet de relâcher la compression exercée par le tendeur sur le corps allongé. Selon l'invention, il est prévu des moyens d'amortissement (50) adaptés à freiner le mouvement et/ou la déformation du tendeur lors de la relâche de la compression.The invention relates to a structural element (1) comprising: - an elongated body (10), - at least one tensioner (20) which compresses the elongated body longitudinally, and - a deactivation means (30) of said tensioner, which allows to release the compression exerted by the tensioner on the elongated body. According to the invention, damping means (50) are provided which are suitable for slowing down the movement and / or the deformation of the tensioner when the compression is released.
