【摘要】 本文结合工程实例,对某框支短肢剪力墙一异形柱框架结构进行了非线性时程分析,介绍了弹塑性地震反应分析中采用的空间整体动力模型、纤维梁元模型、墙元模型及动力微分方程的积分方法。通过分析得到该结构层间位移角包络图和塑性铰分布情况等反映结构性能的指标,分析结果表明:该结构在设防烈度为6度的地区是可行的。更多还原

【Abstract】 This article union project actual example,A reinforced concrete frame supported shortleg shear wall structure with special-shaped columns is studied by nonlinear time history analysis.The 3-D dynamic model,fiber beam element model,wall element model and integration algorithm of dynamic differentia equation used in elastoplastic seismic response analysis are introduced.The envelope diagram of interstorey drift ratio and distributions of hinges are also obtained.Analysis results show that the application of this kind of structure system is applicable in the area of seismic fortification intensity 6.更多还原
