| 摘 要： | 基于流体粘滞阻尼器自身的力学特性,分析了设置流体粘滞阻尼器对大跨度斜拉桥的减震效果,着重分析了阻尼器参数对减震效果的影响。结果表明,流体粘滞阻尼器能显著地减小梁端纵向位移及主塔塔底弯矩,减震效果取决于阻尼器参数的选取。

| Abstract: | In the paper,the mechanical characteristics of fluid viscous dampers are discussed firstly,and then the seismic response reduction of a super long span cable-stayed-bridge by adding fluid viscous dampers is investigated.The emphasis is placed on the influence of damper parameters.The investigation indicates that adding fluid viscous dampers can significantly reduce the girder displacement and the moment at the bottom of tower,and the reduction depends on damper parameters. |
