Abstract:
Post-tensioning of concrete members is a promising field of application for FRP tensile elements. The high tensile strength and good corrosion resistance of FRP can be utilized to compete with prestressing steel tendons. To be able to compete successfully, suitable anchorages for FRP need to be developed. The interactive process of experiments and theoretical models for the development of tendon-anchorage assemblies with high mechanical efficiency is demonstrated. This process is then illustrated for a resin-bonded GFRP anchorage.
