Application of fiber reinforced polymer (FRP) cables on long-span cable-supported bridges can overcome the disadvantages of traditional steel cables such as heavy weight, obvious sag effect, decreasing carrying efficiency, pronounced fatigue degradation, and serious corrosion damage. On the basis of theoretical analyses and experimental studies on the application of FRP cable in long-span cable-supported bridges, the research progress in recent years on the key issues of FRP cables in long-span cable-supported bridges is reviewed in detail. The basic mechanical properties of FRP cables, the static and dynamic behavior of long-span cable-supported bridge with FRP cables, and the economic performance of long-span cable-supported bridges with FRP cables are discussed. The results show that FRP cables have the feasibility to be used in long-span cable-supported bridges from the mechanical properties. However, due to the poor shearing and bending performance of FRP cables, abundant nonlinear dynamic behavior, complex dynamic performance of bridges, and insufficient practical experience, the application of FRP cables in long-span cable-supported bridges is facing great difficulties. Accordingly, the future research directions on the application of FRP cables on the long-span cable-supported bridge are addressed.

在大跨度斜拉桥上使用纤维增强聚合物（FRP）电缆可以克服传统钢缆的缺点，如重量大，下垂效果明显，承载效率降低，明显的疲劳退化和严重的腐蚀破坏。在对FRP电缆在大跨度斜拉桥中应用的理论分析和实验研究的基础上，详细综述了近年来FRP电缆在大跨度斜拉桥中的关键研究进展。讨论了FRP电缆的基本机械性能，大跨度FRP电缆支桥的静态和动态性能以及大跨度FRP电缆支桥的经济性能。结果表明，从机械性能来看，FRP电缆在大跨度斜拉桥中具有可行性。然而，由于玻璃钢电缆的剪切和弯曲性能差，非线性动力学行为丰富，桥梁的动态性能复杂以及实践经验不足，在大跨度斜拉桥中应用玻璃钢电缆面临着很大的困难。因此，提出了将FRP电缆应用于大跨度斜拉桥的未来研究方向。玻璃钢电缆在大跨度桥梁中的应用面临很大的困难。因此，提出了将FRP电缆应用于大跨度斜拉桥的未来研究方向。玻璃钢电缆在大跨度桥梁中的应用面临很大的困难。因此，提出了将FRP电缆应用于大跨度斜拉桥的未来研究方向。
