| Application of Fiber Reinforced Polymers (FRP) which has some excellent properties such as high corrosion resistance or high strength with light weight, to bridge structures will solve some of the problems that we are facing such as corrosion of steels or RC rebar, and is expected to reduce maintenance of infrastructures. Moreover, FRP's possibility is also expected to enable new structures or new functions, such as new retrofit method or new diagnosis method for structures.Based on these view points, Public Works Research Insitute (PWRI) have been carried out many kinds of research and construction developments on the application of FRP including feasibility studies, construction technology of FRP bridges and the associated fundamental technology since early 1980s. In this report, the outlines of those activities are introdued including the presently conducted ones. |
