Evaluation of FRP Tendon-Anchor Systems for Prestressed Concrete Structures

摘要

Much research has already been conducted on the mechanical response of FRP tendons to be used for pre- and post-tensioning concrete structures. This research has been performed primarily outside of the USA and directly by the manufacturers. An experimental investigation was undertakent o provide a domestic evaluation of the mechanical performance of ten different aramid, glass, and carbon FRP tendons, with attention paid to the effects of the anchorage device recommended by the manufacturer. The first phase of the project herein reported consisted of the verification of some tendon-specific properties, namely: ultimate strength, modulus of elasticity, and ultimate strain. It was determined that given the limitation of the experimental program a reasonable correlation exists with manufacturer's values. In most cases, the anchorage devices permitted the tensioning to failure of the FRP tendons.
