Development of a Mechanical Wedge–Barrel Anchor for CFRP Rods: Static and Fatigue Behaviors

In this study, a mechanical anchorage for prestressed carbon fiber–reinforced polymer (CFRP) rods was proposed. The proposed anchorage consisted of a steel barrel with a conical hole and three separate aluminum wedges that are in direct contact with the CFRP rod. The anchorage system relied only upon friction, without any adhesives required. The static and fatigue behaviors of the anchor were experimentally investigated according to the European...
