Abstract—This paper presents the local behavior study of strengthened reinforced concrete short corbel by bonding composite carbon fiber fabrics. Indeed, reinforced concrete short corbels often are used in civil engineering, in buildings. The effect of some parameters on mechanical behavior of structure strengthening is examined. As such as, influence of the type of strengthening by gluing directly on concrete corbel or wrapping. The used fiber fabrics are unidirectional and bidirectional carbon fabrics. The ultimate load and displacement of specimen are compared to the reference structure of static tests monotonous applied load. The cracking and failure mode under static loading are presented. The extensometer technique based on deformation gauge strain is used to study the local behavior of the structure. This technique allows to measure deformations of gauges glued to the surface of the composite fabrics of carbon fibers bonded, of the concrete and of steel.
