摘要
静力弹塑性分析(Pushover)方法是一种在罕遇地震作用下简化结构复杂的弹塑性分析的方法,也是一种基于结构位移的静力分析法[1]。通过Pushover方法可以预估结构的抗震能力,从而确定结构是否能达到相应的抗震性能。本文首先阐述了Pushover分析方法的基本原理,并运用Midas软件对混凝土框架结构模型进行了Pushover分析,考查了结构跨数这一因素对Pushover分析结果的影响。
Static analysis （Pushover） method is structured in rare earthquake analysis of elastic-plastic deformation under the effect of a simplified approach, in essence,is a static analysis method. By Pushover method can estimate the seismic capacity of the structure in order to determine whether the structure can achieve the appropriate seismic performance. This paper first describes the basic principles of Pushover analysis methods, and the use of concrete frame structure Midas software model was Pushover analysis examines the structure of the factors across several Pushover analysis results.
