中文摘要：

以鄂东长江大桥（主跨为926m的斜拉桥）为工程背景，建立该桥梁无控、有间断型TMD和连续型TMD的ANSYS模型，对比分析控制器对桥梁风致竖向抖振的减振效果。间断型TMD是在桥梁结构合适的位置布置一段或几段TMD；连续型TMD是在主跨或全桥上连续布置TMD，两者的控制效果均优于单个TMD。ANSYS计算结果表明，间断型TMD和连续型TMD对桥梁风致竖向抖振的减振效果明显。最后，根据相似比制作桥梁模型，进行无控和安装了连续型TMD的桥梁模型风洞试验，结果表明，连续型TMD对桥梁的风致竖向抖振能起到很好的控制效果。

英文摘要：

The Edong Yangtze River Bridge was taken as the engineering background which is cable-stayed with the main span of 926 meters. The ANSYS models without controller, with discrete TMD （tuned mass damper） and continuous TMD were established for the comparative analysis of the damping effect on the wind-induced vertical buffeting. The discrete TMD was placed appropriately with only one or a few parts while the continuous TMD was set on the main span or all over the bridge. The control of these two types were both superior to that of a single TMD. The ANSYS results show that continuous and discrete TMD have significant damping effects on the win＆induced vertical buffeting of the bridge. Finally, the bridge model was built according to ratio of similitude, and then wind tunnel test was conducted for the bridge model with continuous TMD and without controller. The wind tunnel test results show that continuous TMD has a salutary effect on the wind-induced vertical buffeting of the bridge.
