| 摘 要： | 基于Ｒ．Ｈ．Ｓｃａｎｌａｎ教授的斜拉桥风致抖振分析理论，作者导出了调质阻尼器（ＴＭＤ）作用下斜拉桥弯扭耦合抖振响应的计算公式。经过大量的数据处理，给出了ＴＭＤ参数的优化公式。并以美国的ＢａｙｔｏｗｎＢｒｉｄｇｅ为例，对该桥有无ＴＭＤ情况下的抖振响应作了对比分析，结果表明，被动ＴＭＤ对该桥的抖振具有较好的抑制效果。

| Abstract: | In this paper, based on Prof. Scanlan's theory on buffeting analysis of long-span bridges, the authors derive formulas for bending and torsion coupled motion with Tuned Mass Damper(TMD) . By Processing a lot of data, the optimal formulas of the parameters of TMD for engineering purposes are derived. Finally, the Baytown Bridge is taken as an example to make a comparison of the responses of the bridge with and without TMD, the result shows that the passive TMD has a good effectiveness for suppressing the buffeting of the bridge. |
