摘要

基于结构性态的抗震设计思想已在许多规范中采纳,但碍于分析手段的限制,尚未在工程实践中全面采用。文中针对pushover的基本假设,提出三条标准用于判断pushover分析结果的准确性。以实际工程为例,采用ETABS进行pushover分析,评价中震和大震作用下的结构性能。通过比较预定的抗震性能目标,调整结构设计,从而实现用pushover分析结果指导结构抗震设计,对实际结构设计有很好的参考价值。
The idea of seismic design based on structural performance has been adopted in many codes,but is not put into practice popularly because of the limit of the analysis method.In this paper,three criterions about assumption rationality were supposed to judge the result of pushover analysis.A real structure was analyzed by pushover method with ETABS,and the structural performance under moderate and severe earthquake were obtained.Compared with the structural seismic performance predefined,the structural design was modified.The application of pushover analysis in seismic performance design was investigated,which was proved to be valuable in practice.
