الملخص

L’un des problèmes majeurs dans le domaine de la construction est la dégradation configurations de renforcement, les gains en termes de ductilité globale de la structure ainsi qu’en termes d’augmentation de la charge portante ont été vérifiés. Outre ces aspects quantitatifs, ce travail a permis de proposer des pistes pour l’établissement de règles de dimensionnement de ces renforts spécifiques à la réhabilitation des structures, en lien avec les normes actuelles (BAEL).Pour cela plusieurs méthodes ont été établis pour le calcul de la section du composite qui dépend de différents paramètres qui influent sur le dimensionnement des éléments structurels renforcés : la géométrie de la section, les caractéristiques des matériaux utilisées. () One of the major problems in the field of construction is the degradation of Structures. Most of the structures show signs of weakness and no longer meet or will no longer meet the requirements for which they were designed. The causes are multiple, we can cite errors during the study or execution, an increase in loads, a change in the operation of the structure, corrosion of the reinforcements, accidental actions such as earthquakes or shocks The appearance of these problems the reinforcement of structural elements by bonded composite materials, but the design rules regarding the application such reinforcement materials have not yet all been clearly established. The present work aims to contribute to the establishment of these rules for the reinforcement of reinforced concrete structures by composite materials. An analytical study was therefore carried out on the different reinforced concrete elements (beams, slabs and columns), has been undertaken, and compared with others analytical models. The purpose study was to evaluate the effectiveness of the different strengthening configurations in increasing the dissipated energy and the ductility. In addition to the quantitative aspects, it was made possible to propose design rules for the use of FRP in structural rehabilitation, linked to current rules (BAEL).There is many studies were established for the design of FRP area which depends with different strengthening configurations and influence on design of reinforced structural elements: geometric of FRParea, characterized of used material.
