Abstract

L'invention concerne un câble de précontrainte destiné à être placé au sein d'une structure précontrainte, ledit câble comprenant un ou plusieurs torons clairs et étant destiné à être injecté avec un coulis de ciment, caractérisé en ce qu'il comprend au moins un élément qui participe à la précontrainte et dont la tension mécanique est mesurable. L'invention porte également sur un dispositif de détection de la rupture d'au moins un toron d'un tel câble de précontrainte, sur un ensemble comprenant le dispositif et le câble, sur une structure précontrainte comprenant au moins un tel câble, sur un procédé de détection de la rupture d'au moins un toron d'un tel câble, ainsi que sur un procédé de mise en tension des éléments d'un tel câble.
