偏心结构地震反应分析及改善摘 要:大量震害分析和观察表明,结构在地震发生时存在着扭转振动,且在地震作用下结构的平扭耦合效应是不可忽视的,在某些情况下甚至是结构破坏的主因
本文总结归纳了前人的讨论成果,对偏心建筑结构弹塑性抗震性能以及影响参数进行了探讨,提出目前存在的问题和分歧,给出一些有建设性的建议,以便于进一步深化讨论
关键词: 偏心结构 弹塑性 平扭耦合 规则性Design and Research ofSeismic Response of Eccentric StructureAbstract: Lots of earthquake disaster phenomena show that structures with torsion modes of vibration have obvious torsions under seismic action, which are occurred together with translational vibration of structures
In certain cases, torsion can be the main action of the structural damage
In this paper,pass research is reviewed
This paper focus on the elastic-plastic seismic performance of high rise structure and its main parameters of eccentric structure
Some existing issues and bifurcations as well as some constructive proposals are given in t
