Method of active reinforcement against cutting effort or punching on structural carrier elements, and active reinforcement system (Machine-translation by Google Translate, not legally binding)

Method of active reinforcement against shear stress or punching in structural bearing elements, of the type of beams, pillars and slabs, in which an arrangement of at least one bar, wire or similar reinforcement element (3) of alloy with memory is made in a pre-stretched form in martensitic phase around the structural bearing element (1) to be reinforced, transversely to a fissure (2) generated, or that may be generated, by the shear stress or punching. Subsequently an anchoring of the bar, wire or similar reinforcing element (3) around the structural support element (1) is performed, and an activation of this bar, wire or similar reinforcing element (3) by heating, causing its transformation from martensitic phase to austenitic phase. Additionally, the invention relates to an active reinforcement system with at least one bar, wire or similar reinforcing element (3) of alloy with shape memory.

Posteriormente se realiza un anclaje de la barra, alambre o elemento similar de refuerzo (3) alrededor del elemento portante estructural (1), y una activación de esta barra, alambre o elemento similar de refuerzo (3) mediante calentamiento, originando su transformación de fase martensítica a fase austenítica. Adicionalmente la invención se refiere a un sistema de refuerzo activo con al menos una barra, alambre o elemento similar de refuerzo (3) de aleación con memoria de forma.
