Abstract
Most of the existing fibre-reinforced polymer (FRP) strengthening systems are wrapped directly to the structure creating a “2-material repair system”, i.e. the existing structure and the FRP wrapping. Recently, a new type of FRP composite jacket with an innovative mechanical joining system for repair of existing structures has been developed. This repair system works by wrapping the prefabricated FRP jacket around the damaged structure and placing a grout infill between the jacket and the damaged structure producing a cylindrical confinement and creating a “3-material repair system”. The effective assembly of the components, the existing structure, the grout infill and the FRP jacket, is the key for the effective utilisation of this repair system. This paper reviews and evaluates the important parameters that affect the behaviour of structures repaired with the novel FRP jacket to ensure its structural integrity and efficiency.
