摘　　要：针对水平地震作用，系统分析了ＴＭＤ在单层鞍壳振动控制中因质量变化、分布位置变化、所控振型个数变化对其结构控制效果的影响及其敏感性问题．并得出了一些重要结论．A relatively complete parametric studies of TMD (tuned mass damper) systems in vibration control of single layer latticed saddle shells are presented. Through the random vibration analysis and simulated analysis of time course of single layer latticed saddle shells under the disturbances of horizontal earthquakes, the valuable conclusions are reached with the effects of the mass, the control action distribution and the number of vibration mode control. Besides, the effectiveness of TMD systems is also considered.
