Experimental Study of the Wedge-sleeve Anchorage of CFRP Tendons

To reduce stress peak value between wedge and CFRP tendon,a new wedge-sleeve anchorage of CFRP tendon is developed.The anchoring capacities of the new wedge-sleeve anchorage of CFRP tendon under static loading,fatigue loading and periodic loading are tested.The experimental results show that various parts of the anchorage can coordinate to work,while,the anchorage efficiency coefficients of anchor assembly under static loading are more than 0.95,and the fatigue performance and periodic performance are excellent.The improved wedge-sleeve anchorage can efficiently anchor the used CFRP tendons and has potential engineering application.
