Title: Influence of Girder Vibration on Cable Damper's Performance of A Cable-stayed Bridge
Abstract: The model combined by cable,girder and damper is founded to study the influence of girder vibration on cable damper ’s performance of a cable-stayed bridge. The complex mode method and nondimensionalization are used to analyze the relationship between the girder’s parameters and the performance of cable-related damper. The results indicate that the performance of cable-related damper will decrease greatly when the girder frequencies are near the frequencies of cable. The smaller absolute displacement of damper’s piston caused by the very small vibration phase shift of girder and cable is the physical cause of the negative impact mentioned above.
