| Abstract: | As rain-wind induced vibration of cable threatens the security of cable-stayed bridges, it is one of the hot researches of bridge. Damages due to rain-wind induced vibrations are introduced, research methods including field observation, wind tunnel test, theoretical analysis, computational fluid dynamics are illustrated. The possible mechanism of the vibration is analysed, present countermeasures are introduced, and problems to be solved are pointed out. |
