Stay cables of the long - span cable - stayed bridges are susceptible to vibration under wind loading, or wind incorporated rain excitation, or deck motion due to high flexibility, relatively small mass and very low inherent damping, such as vortex shedding, wake galloping, parameter resonance and wind - rain induced vibration. large - amplitude vibration of cables may reduce the life of cables and threaten safe traffic, and has been considered today as one of the most critical problems for this type of bridge
大跨度斜拉橋拉索具有較小的質量和極低的阻尼，在風、風雨及橋面振動等外部激勵下極易發生振動，如渦激共振、尾流馳振、參數共振和風雨振等，拉索的大幅振動對拉索的使用壽命和橋梁安全運營構成極大威脅，它已成為大跨度斜拉橋急需解決的關鍵問題之一。
