Pull-Out Behavior of CFRP Single-Strap Ground Anchors

Pull-out experiments were performed on four carbon fiber–reinforced polymer (CFRP) ground anchors simulating their applications in rock and soil. The CFRP tendons used in these anchors comprise a single-strap end on both ground and air sides. On the ground side, the single-strap end is embedded in a prefabricated cylinder of high-strength grout that fits into the borehole. In rock applications, the ground-side anchor can be used without...
