Abstract: Reinforced Concrete structures are suffering from various deteriorations like corrosion, cracks, spalling and large deflection. These deteriorations are caused by various factors such as aging, corrosion of steel reinforcement, environmental effects and accidental impacts on the structure. There are several options available for retrofitting the structural members of the existing reinforced concrete structures. Bonding of thin steel plates is the common method of retrofitting. Nowadays, bonding using fiber reinforced polymer sheets on to the damaged members helps to increase load carrying capacity, ductility and stiffness of the damaged structure. Such technique is an effective way to improve the flexural and shear performance of the reinforced concrete damaged structure. This project mainly focused on retrofitting the corrosion damaged reinforced concrete beams using mechanically fastened carbon fiber reinforced laminates. This type of retrofitting increases the load carrying capacity of the corrosion damaged reinforced concrete beams. It also increases the flexural and fatigue strength of the damaged reinforced concrete beam. Here, the general review of literature on the reinforced concrete structures, in which FRP used for strengthening purpose, is briefly presented and they were listed in the references at the end of the report.
