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 economy in our country, more and more high-rise buildings are used in practical projects. How to evaluate and ensure its reliability under earthquake has become the subject of many earthquake-resistant workers. The necessity of conducting elasto-plastic dynamic time history analysis and the research methods and advantages of elasto-plastic dynamic time history analysis are introduced. Through elastic-plastic dynamic time-history analysis of specific cases, the interlayer displacement, the maximum displacement and the harmful layer displacement of the structure are obtained to find out the weak parts of the structure. The yield and failure rules of the components are analyzed and the seismic performance of the structure is evaluated.
