Abstract

L'invention concerne un portique utilisé pour la construction de ponts, de viaducs ou d'autres structures. Ce portique est équipé d'un système permettant de régler automatiquement la précontrainte de la structure de ce portique en fonction des actions extérieures exercées sur ladite structure au moment du chargement. Le réglage de la précontrainte s'effectue par l'intermédiaire d'au moins un détecteur (2) qui contrôle la structure, lesdits détecteurs transférant ces mesures à un contrôleur (6) pouvant ensuite exciter au moins un organe de commande modifiant la tension du ou des câbles de précontrainte de cette structure. Parmi les nombreux avantages de l'invention, l'un consiste en la possibilité d'application d'un niveau élevé de précontrainte sans provoquer de déformations indésirables de la structure principale (1) dans le cas de l'absence d'application de charges extérieures.
