【摘要】 在强烈地震作用下,结构的薄弱层往往率先发生弹塑性变形集中,甚至造成结构局部或整体倒塌。而静力弹塑性分析(Push-over)方法作为一种简单而有效的结构抗震能力评价工具,可以较为快捷地判明结构的薄弱部位,并用于指导结构的抗震设计。本文简要介绍了Push-over分析的实施步骤,并运用结构通用分析软件SAP2000对几种典型不规则形式的结构进行了分析,说明Push-over分析方法在探测结构薄弱部位方面的实用性。更多还原

【Abstract】 Under strong earthquake, the weak story of a structure always leads to the centralization of elasto-plastic deformation and collapse As a simple but effective tool for the assessment of structural seismic capacity - Push-over analysis may conveniently distinguish the weakness of structures, which play an important part in the seismic design. This paper presents a concise introduction to the Push-over analysis method and several irregular frames are studied by SAP2000 based on Push-over analysis It is concluded that Push-over analysis can detect the weakness of structures effectively.更多还原
