| 摘 要： | 提出在桥塔和主梁之间安装6个粘滞阻尼器（VD）及在主梁跨中2箱中各设置9个侧向调谐质量阻尼器（TMD）的混合控制系统来控制桥梁侧向抖振响应的方案.以某大跨度桥梁为例建立三维空间有限元模型,利用谐波合成法模拟桥梁脉动风荷载,通过与无控结构、仅安装VD结构、仅安装TMD结构的桥梁有限元模型进行了对比分析,结果表明：在侧向风... |

| Abstract: | A mixed control system,including six visvous dampers(VD) installed between the tower and main beam of the bridge and 9 lateral TMD installed in the two boxes in the main beam span,was proposed to resolve the problem of the wind-induced lateral buffeting of bridges.A three-dimensional finite element model based on an example of a long-span bridge was built,and the harmonic synthesis simulation was used to simulate the wind loads for bridges.By conducting a comparative analysis and calculation of the finite e... |
