Identification of parameters of a behaviour model for concrete structures
Description
In this report for an accreditation to supervise research, the author proposes an overview of his works which specifically addressed the identification of parameters of a behaviour model for concrete. He first presents and discusses the choice of the identification method by testing different conventional methods on simple and representative examples. He reports the application of the identification on structures with dynamic and degradation problems. He discusses scale effects and notably outlines the relevancy of the used behaviour model to describe simulated phenomena. He reports the development and performance of a zooming method for the description of the evolution of localised cracks within structures. He concludes on perspectives for his research laboratory
Abstract (French)
Ce memoire comporte quatre parties: - La premiere partie presente le choix de la methode d'identification adoptee. Ce choix est effectue en testant differentes methodes classiques sur des exemples simples et representatifs des problemes rencontres. - La seconde partie montre l'application de l'identification sur des structures de problemes dynamiques et de degradation. - La troisieme partie traite des effets d'echelle. On montre notamment la pertinence du modele de comportement utilise pour decrire les phenomenes simules. - La quatrieme partie presente le developpement et la performance d'une methode de zoom pour decrire l'evolution de fissures localisees au sein d'une structure. La conclusion et les perspectives portent sur mes travaux actuels au sein du Laboratoire de Mecanique et Genie Civil de Montpellier depuis l'annee 2003. Ces travaux font l'objet d'une conversion thematique. En effet, ils restent dans la continuite des precedents mais portent sur l'identification de l'etat d'endommagement de structures de tensegrite. Ces structures legeres sont des treillis composes de barres reliees entre elles par des cables tendus. Le but de l'etude est de determiner les pertes de tension dans les cables qui assurent la stabilite de l'ensemble. (auteur)Files
