This paper describes an experimental analysis of damaged concrete corbel strengthened by gluing carbon fibre composite fabrics. The purpose of the investigation is to study all changes in behaviour and then their contribution to a better understanding of reinforced concrete corbel. Five reinforced concrete corbels are tested under tree-points bending to failure. Four of them are damaged at different load level up to 80% before strengthening. Test results show that strengthened corbel specimens using glue given an ...
