摘要：
The example of application of a tuned mass damper to a cable-stayed bridge during construction is illustrated; design, analysis, manufacture, installation and maintenance. A linear active mass damper system is proposed and developed to reduce vibration of long-span bridges subjected to wind loads. The linear active mass damper system was designed and built for a scaled bridge model; furthermore, the system was designed to reduce vibration in two degrees of freedom. Wind tunnel test was carried out with the damper deactivated and activated to evaluate the performance of the system. Test results showed that the linear active mass damper system was able to control wind-induced torsional rotation and vertical displacement with high efficiency. In addition, the AMD mock-up test with a scale of 1/10.5 was carried out for the vertical direction. We could find the vibration control effects through the performance test.
