【摘要】 对一个框架结构实例进行静力非线性推覆(Pushover)分析。分析结构基底剪力-顶点位移之间的弹-塑性变化关系、结构塑性铰的形成历程和破坏机制,得到结构的性能点;检验结构的层间位移角是否满足GB 50011—2011《建筑抗震设计规范》规定的层间位移角的限值,以检验和考察它们的抗震能力,探讨结构的破坏机理,寻求改善结构抗震性能的方法。更多还原

【Abstract】 It was conducted the static nonlinear pushover analysis of a moment frame structure.Through the analysis of the structure basis shearing force-top displacement’s elastoplasticity change relations,the structure plastic hinge’s formation course and the destruction mechanism,it was obtained the performance point of the structure.Then it was examined the story displacement of the structure to see whether it satisfied the limit of the story displacement specified by the code GB 50011—2011,so as to examine and inspect the earthquake resistance ability.Finally the structure failure mechanism was discussed,and the method of improving structure earthquake resistance performance was researched.更多还原
