Beikou Bridge
Beikou Bridge is a river-crossing passage connecting Huanghua of Yueqing and Lingkun Island in Wenzhou City, Zhejiang Province, China. Located over the Estuary of the Ou River, it is a control project for the G1523 Ningbo-Taizhou-Wenzhou Expressway Auxiliary Line (National Expressway) to cross the Ou River. The main bridge adopts a span arrangement of (230+800+800+348) meters and is the world's first three-pylon four-span double-deck steel truss girder suspension bridge.
The bridge was completed and opened to traffic in May 2022, with 4 sets of viscous dampers applied. The model and parameters are as follows:
Model | Damping Force（kN） | Displacement（±mm） | Qty（set） |
FVD-2000/±680 | 2000 | 680 | 4 |
