摘要
利用静力弹塑性分析对拟建结构进行抗震性能设计,分析结构在地震作用下从构件到结构多层面的弹塑性性能,方法概念清楚,实施相对简单。以一框架-剪力墙高层建筑为例,利用SAP2000软件对结构进行静力弹塑性分析,评估结构的抗震性能,考察结构方案的合理性、经济性,重点关注转换构件、错层柱、底部剪力墙、连梁等关键部位的塑性发展情况,为结构设计优化提供依据。
Pushover analysis could be used for the seismic performance design of a proposed building to analyze the plastic performance of the elements and the whole structure. This method is relatively easy, operable and useful for engineering application. Taking a RC frame-shear wall building as an example, SAP2000 was used for the Pushover analysis to evaluate the structural seismic performance and focus on the key components of the structure, such as transform elements, short columns, bottom shear wall, coupling beams and etc. The analysis results have played a role in the evaluation of the structural scheme and the design optimization.
