Abstract:
FRP are new materials for structural engineers. Therefore, an overview on the important fiber properties, matrix resins, and composite elements becomes necessary to show the assets and drawbacks of FRP and to illustrate their potentials and limits. Besides several other fields, concrete prestressing seems to have become a promising field of application of FRP. In prestressed concrete construction, high strength and good corrosion resistance of FRP can be utilized optimally. In this field of application, FRP can compete with prestressing steel, especially in such cases in which the corrosion protection of prestressing steel becomes expensive or remains tarnished by residual risks. The post-tensioning of concrete structures requires anchorages with a high mechanical efficiency. The main avenues of development are discussed, and the necessary future research is outlined.
