Abstract

A fiber-reinforced plastic (FRP) is a composite material of fibrous re- inforcement such as carbon fiber, aramid fiber or glass fiber combined with a plastic matrix, which is normally epoxy or vinyl ester resin. This new structural material has high strength, is light in weight, non- magnetic, nonconductive and durable. Before using it as tendons for bridge strengthening, it is necessary to clarify its long-term basic prop- erties, which are important factors in determining the critical tensile stress values. Creep rupture tests were conducted using tendons of carbon fiber-reinforced plastic (CFRP) and aramid fiber-reinforced plastic (AFRP). The correlation between creep rupture time and ap- plied load was examined experimentally and design reference values were determined.
