静力弹塑性Push-over分析方法在名人国际结构设计中的应用
|
摘要
结构静力弹塑性分析(push-over)方法近年来在国外已成为结构抗震能力评估的流行方法,并得到了国内广大学者的重视。本文介绍了该方法的基本原理和实施步骤,并运用该方法对一幢22层框架-剪力墙结构进行了分析,得到了性能点处的层位移、层间位移角曲线和塑性铰分布。计算结果表明,该结构符合"强柱弱梁"的原则,能满足大震不倒的设防要求。
In recent years, the analysis method of push-over has already become apopular way to estimate the quakeproof ability of the building structure and lots of do-mestic scholars begin to attach importance to it.This article covers the fundamentalprinciple and implementing steps of the method and through the analysis for a 22-storeyed frame-shear wall structure by using this method, the storey drift and its cornercutting curves and plastic hinge distribution of performance points have been calculated,which shows this kind of structure accords with the principle of"strong column andweak beam"and meets the fortification demand for not collapsing under severe earthquake.
