| Abstract: | Sutong bridge is located in the estuary of Yangtze river with the main span of 1088 meter. Because of the effects of monsoon climate, stayed cable vibration is a project difficulty which has to be solved. One of the most vibration common damping measures is to install mechanical damping device near the anchorage zone of stayed cable. This paper introduces the structure and vibration damping mechanism of the damping. |
