Abstract: In order to study the fatigue performance of adhesive anchorage system for CFRP tendon, epoxy resin mixed with sand was adopted as bond medium to make the bond-type anchorage systems for CFRP tendon, and they are tested under different cyclic loading conditions. Then the static performance of these systems which have experienced fatigue loading was inspected by static load test. The result shows as follows: ①a certain degree of fatigue loading is benefit to improve the synergistic effect and anchorage performance of the system. With the increasing of cycles, the relative position of the two ends of the anchorage system tends to be more stable. When P-1, P-2 and P-3 were loaded to 200,000, 150,000 and 700,000 times, respectively, the relative displacement no longer increased and the system entered into a stable state. ②The fatigue loading improved the bond performance of the anchorage system when the tensile loadwas low, while it was declined when the load was high.
