摘要：
Fiber reinforced polymer (FRP) have excellent properties such as high strength, corrosion resistance and light weight compared with traditional steel cables. However, how to fully utilize these properties and achieve reliable anchorage of FRP cables has been an obstacle to the large-scale and commercial application of FRP cables. FRP cables-anchorage system consists of non-metallic FRP cables and customized anchorages, whose research and application have become one of hot topics in civil engineering. In order to promote the development and application of FRP cables-anchorage system, the research status of FRP cables-anchorage system were summarized from its classification, static load anchorage performance, long-term performance and fatigue performance. Furthermore its application in actual bridge projects was introduced. Firstly, the classification of FRP cables-anchorage systems was introduced. Various types of bond-, wedge- and composite-type anchorage systems with different construction forms and composition materials were systematically sorted out and their characteristics were compared. Then, the factors affecting the static anchorage performance, long-term performance and fatigue performance of different types of FRP tendons-anchorage system were analyzed, and the performance mechanisms of various types of anchorage systems were explored. On this basis, the finite element analysis method and analytical analysis method were elaborated. Next, the practical projects using carbon fiber reinforced polymer (CFRP) cables-anchorage systems in China and abroad were summarized, and the application scenarios and basic configurations of CFRP cables-anchorage systems were introduced, and the design features of each anchorage system were presented. Finally, the existing problems and future development trend of FRP cables-anchorage system were discussed in order to provide reference for academic research and engineering practice of FRP cables-anchorage system. © 2023 Editorial Office of China Civil Engineering Journal.
