Applications of Fiber Reinforced Plastic in Structure Rehabilitation in Civil Engineering

The applications of Fiber Reinforced Plastic(FRP) materials in the structure rehabilitation is discussed and compared with steel-bonded reinforcement. The related studies are systematically reviewed and analyzed. Some suggestions for the further researches in the future are put forward. First, the innovation should be emphasized for modification technology of high performance FRP and matching materials. Second, the conventional theory is not applicable to FRP, so the theoretical study should be carried out for structure rehabilitation by FRP. Third, the construction technology for the rehabilitation structure should be further developed. Fourth, because a widely accepted standard of the FRP detection technique is not available, studies in that direction are desirable. It is shown that the FRP structure rehabilitation can reduce the time and cost for maintenance, and the disturbance for traffic, and improve durability. It will play an important role in the structure rehabilitation field.
