摘要
对于复杂高层结构,通常的分析方法主要有振型分解反应谱法、弹性时程分析法、静力弹塑性(pushover)分析方法等。而对于高度较高、周期较长及受高阶振型影响较大的结构,动力弹塑性分析方法能更准确地分析地震作用对此类结构的影响。该文结合中交南方总部大楼项目,运用Perform-3D程序对其进行了罕遇地震下的动力弹塑性分析,得出了结构在罕遇地震作用下的动力响应及关键部位、关键构件的塑性发展情况,对结构大震性能作出评价。
The most common analysis method of complex highrise buildings is the response spectrum analysis,elastic time history analysis,pushover analysis and etc.For the analysis of those highrise buildings whose height is higher than 200 meters,their natural periods are longer than 4 seconds,the dynamic nonlinear analysis would be more accurate.In this paper,the dynamic nonlinear analysis was executed by using the Perform-3D program.Through the analysis,the structural dynamic response and plastic stages due to a rare earthquake were obtained,which also satisfied the seismic performance objectives of Chinese design code.
