Abstract
In recent years, rehabilitation has been the subject of extensive research due to the increased spending on building maintenance work and restoration of built works. In all cases, it is essential to carry out methods of reinforcement or maintenance of structural elements, following an inspection analysis and methodology of a correct diagnosis. This research focuses on the calculation of the necessary reinforcement sections of carbon fiber for structural elements with reinforced concrete in order to improve their load bearing capacity and rigidity. The different results obtained reveal a considerable gain in resistance and deformation capacity of reinforced sections without significant increase in the weight of the rehabilitated elements.

IntroductionThe method which has emerged in recent years is the reinforcement by composite materials [2]
The disorders occurring in structures are often due to the degradation of the materials used, or the change in the load of the structure.The deterioration of materials over time, or the structural modification of buildings spur the development of efficient technologies of reinforcement.The overriding criteria in the evaluation of these technologies are the sustainability of the technology solution and the lowering of the implementation constraints [1].The method which has emerged in recent years is the reinforcement by composite materials [2]
This method uses the bonding of composite plates (Textile unidirectional or bidirectional reinforcement, strips, carbon fibers...) or in situ direct lamination of composites associated to thermosetting polymer matrices
Summary
The method which has emerged in recent years is the reinforcement by composite materials [2] This method uses the bonding of composite plates (Textile unidirectional or bidirectional reinforcement, strips, carbon fibers...) or in situ direct lamination of composites (textile fabrics, glass or carbon) associated to thermosetting polymer matrices (epoxy resins, polyester ...). This technique of reinforcement is an innovative alternative to the traditional solution using bonding metal plates. The development of this technology in the USA and Europe is due to the need of reinforcing the aged structures or the ones which their functionality has changed
