FRPs for structural rehabilitation: a survey of recent progress

Fibre-reinforced polymers (FRPs) are rapidly being introduced into a wide variety of civil engineering applications. These materials have been found to be particularly attractive for applications involving the strengthening and rehabilitation of existing structures. In this paper, progress since 1997, with regard to the rehabilitation of civil engineering structures using FRPs, is reviewed. The repair techniques include: column strengthening and seismic applications using FRP wraps, beam strengthening with bonded FRP wraps and laminates, as well as applications to masonry and other types of structures. Durability considerations when using FRPs for rehabilitation are also discussed, and progress regarding field implementations and assessments is reviewed. Finally, initiatives concerning the development of design guidelines and codes of practice are addressed.
