| 摘 要： | 地震作用下高层建筑动力响应分析对高层建筑的安全设计是不可缺少的.针对高层建筑的受力特点,运用结构分析软件ETABS和振型分解法,对双塔楼结构在水平地震作用下的动力方程进行了分析,对振型和振型参与系数的选取进行了探讨,并对计算模型的选取进行了讨论.在检验结构的抗震性能的同时也验证了模型的可行性和高层建筑结构振型的复杂性.

| Abstract: | The studies of the dynamic response of high-rise buildings under earthquake conditions are necessary for structural safety designing.In accordance with the properties of high-rise buildings,by using the structure analysis software ETABS and the Spectrum Analysis Method,the authors conducted a study of the dynamic characteristics and dynamic analysis response of a twin-tower structure with an enlarged base under horizontal earthquake conditions.The selection of mode shapes' number,suitable selection principles and affecting factors were discussed as well.At the same time,the complicated vibration shapes and suitable mode shape were tested. |
