Abstract

L'invention concerne un procédé et un dispositif pour fournir un support latéral contre le flambement pour une barre d'acier réceptrice d'efforts formant un noyau interne, au niveau d'une région située entre l'extrémité de l'ensemble barre résistant au flambement et les plaques d'acier de l'ensemble de jonction avec le cadre porteur. Un support latéral contre le flambement au niveau de la zone de transition entre une barre résistant au flambement et un élément de cadre porteur est fourni par un élément de barre mécanique d'extrémité comprenant une pluralité de structures de support latérales configurées pour s'accoupler de manière à coulisser les unes relativement aux autres en réponse à une déformation axiale d'une barre d'acier réceptrice d'efforts formant le noyau interne. De cette manière, un effort axial est uniquement supporté par la barre d'acier réceptrice d'efforts formant le noyau interne, pourvue d'une retenue latérale continue.
