Reinforced and prestressed concrete (RC and PC) structures are facing a worldwide problem, which is the corrosion of steel as a result of aging and aggressive environments. Steel corrosion leads to member degradation, endangers structural integrity, and may even cause catastrophic failures. Research has been carried out to find the solution for this problem. Fiber-reinforced polymers (FRP) have been proposed for use in lieu of steel prestressing tendons in concrete structures. The promise of FRP materials lies in their high strength, lightweight and noncorrosive, nonconducting, and nonmagnetic properties.

The interest in the use of FRP composites in PC is mainly based on durability issues. Corrosion of prestressing steel tendons can cause severe deterioration of infrastructure. Properties such as high tensile strength and high resistance to corrosion make FRP composites good candidates for prestressed and posttensioned tendons. Moreover, unlike steel RC sections, members reinforced with FRP bars have relatively small stiffness after cracking. Therefore, serviceability requirements have also been examined. Furthermore, premature creep rupture and weak transverse properties of FRP tendons provide peculiar issues in prestressing application.
