Study on Wind-Induced Vibration Control of a Long-Span Cable-Stayed Bridge Using TMD-Type Counterweight

AbstractIt has been widely acknowledged that a tuned mass damper (TMD) can effectively control the wind-induced vibration of the main deck of long-span bridges. However, the unfavorable effect on static characteristics of the increased dead load cannot be avoided if the TMD is installed straight on the main deck. A TMD-type counterweight is designed in this paper, where the counterweight originally designed for reducing the live load–induced displacements at the central span are taken as the mass block in the TMD. The Sutong Cable-Stayed Bridge (SCB), with a main span of 1,088 m, is taken as an example. The buffeting responses of the bridge with the stationary counterweight and the proposed TMD-type counterweight are compared, and the control performance of the bridge with and without auxiliary piers is also investigated. Results indicate that the TMD has notable effects on reducing the vibration of the main deck without auxiliary piers, whereas the impact is not significant for the presence of the auxili...
