RC frames, when subjected to earthquake, must dissipate large amounts of energy. This can be achieved when the beam-column joints are designed in such a way that the plastic hinges form at a distance away from the column and the joint region remains elastic. In existing frames, a practical way to implement this behaviour is to use FRPs. In this study, two plain scaled-down sub-assemblies and five retrofitted/repaired specimens using a new technique called web-bonded FRP were tested under monotonic/cyclic loads. It was concluded that the use of FRPs can restore/upgrade the integrity of the joint, keeping/improving its strength, stiffness and ductility, and can relocate the plastic hinges away from the column. An analytical model was developed to calculate the ultimate moment capacity of the web-bonded FRP sections considering FRP rupture and tension failure modes. Design charts were also.
