摘　　要：高层建筑非弹性地震反应估计是当前结构抗震研究迫切希望解决的课题。本文概略介绍了常用非弹性地震反应分析方法在高层结构分析中应用的主要问题,从而引出利用等位移原则(对于长周期体系,弹性与非弹性地震位移反应近似相等)进行高层结构非弹性地震反应估计研究的原因,并以长周期单自由度和多自由度体系弹性与非弹性地震反应之间关系的有关研究结果论述了其可行性。The evaluation of inelastic response for high-rise buildings is one of the key problems in the study of earthquake resistance of buildings. In this paper the main problems in modeling inelastic seismic response of high-rise buildings are briefly summarized. The feasibility of using equal seismic displacement principle (seismic displacement responses are nearly equal between long period elastic system and inelastic system) to evaluate displacement response of inelastic system is described based on the summary of the research results concerning the relations between elastic and inelastic responses of systems with single or multiple degree of freedom.
