摘　　要：本文阐述了Pushover分析中改进能力谱方法的概念和实施步骤;对不同场地条件下四个中、低层框架结构采用改进能力谱方法估计的目标位移和非线性时程反应分析结果进行了比较,分析,并提供了不同场地条件下两种方法的相对误差,为该方法的实际应用提供了一些参考依据。In this paper, the fundamental concept and implementing procedure of improved capacity spectrum method are introduced. The target displacements of four middle and low frame concrete structures in different types of site estimated by improved capacity spectrum method and inelastic dynamic history analysis are compared and analyzed. The relatively errors of two methods are shown and some reference basis of capacity spectrum method for application is presented.
