强震作用下某超高层建筑抗震性能分析

SEISMIC PERFORMANCE ANALYSIS OF A HIGH-RISE BUILDING UNDER THE ACTION OF SERIOUS EARTHQUAKE

随着我国经济的发展,超限高层建筑越来越多的应用于实际工程之中,如何评估和保证其在地震作用下的可靠性,已经成为众多结构抗震工作者研究的课题。介绍了开展弹塑性动力时程分析研究的必要性以及进行弹塑性动力时程分析的研究方法及其优势。通过对具体案例进行弹塑性动力时程分析,得到结构的层间位移、最大位移、有害层间位移,从而找出结构的薄弱部位,分析构件的屈服和破坏规律,对结构进行抗震性能评估。

With the development of our national economy,more and more high-rise buildings are coming to our eyes.The subject of how to evaluate and ensure the seismic reliability of buildings is studied by structural seismic workers.This paper introduces the necessity of the research on the elastic-plastic time-history analysis,as well as the advantages of elastic-plastic time-history analysis.By analyzing a specific case,the interlayer displacement of the structure,the maximum displacement,the destructive interlayer displacement were got,so as to find out the weak parts of the structure,analyse the laws of the yield and failure of the components,and evaluate the seismic performance of the structure.
