| 摘 要： | 文章对比分析了一个不规则高层钢筋混凝土框-剪结构和在原结构基础上增设偏心支撑后的新结构的抗震性能，比较了它们的自振特性以及层间位移等地震作用效应。针对不规则高层建筑在地震作用下不可避免的扭转振动问题，提出在结构中适当地增设偏心支撑来减小结构的扭转振动效应及其它结构地震反应这种简单可行、经济适用的方法。

| Abstract: | A seismic analysis of two structures (an irregular high-rise building and the previous structure, in which the eccentric braces are set) is performed to study their torsional vibration response during earthquake. Their free vibration characters and displacements between adjacent floors are compared. It is found that adding some eccentric braces properly can reduce the response of torsional vibration and other seismic response of the structures effectively. The example mentioned in the paper proves that this method is a simple and economical one. |
