Abstract


The reinforcement of the reinforced concrete structures is one of the curative methods used for the rehabilitation of the structures in order to ensure its service and long life period. Various techniques of reinforcement appeared. The first to be used is the joining of steel elements on the surfaces exposed to the stresses due to the loading forces. With the appearance of fibre reinforced polymers (FRP), and in order to avoid the problems involved in the use of steel (corrosion, weight, etc.), the elements of reinforcement are increasingly manufactured with this new type of material. However, these structures present new scientific problems and in particular the mode of failure. The aim of this article is the theoretical and numerical study of the behaviour to failure under three points (coupling bending-shearing) of a reinforced concrete beam reinforced and repaired using carbon fibre plates in order to find a methodology of dimensioning by taking in account the effect of the behaviour of various materials: reinforced concrete, adhesive and composite materials. The results found show that the joining of composite materials on reinforced concrete structures gives an increase in the ultimate load and a reduction in the deformations in the concrete and steels
