【摘要】 以某框架-剪力墙基础隔震结构设计实例为基础,考虑隔震装置的弹塑性本构模型和上部混凝土框架-剪力墙结构的弹性本构模型建立有限元分析模型进行定量分析,研究该框架-剪力墙基础隔震结构的动力响应;在设防地震作用下该隔震支座的非线性滞回特性符合支座设计基本要求,采用基础隔震技术后该基础隔震结构的加速度响应明显减少,分析结果表明框架-剪力墙基础隔震体系隔震和减震效果良好。更多还原

【Abstract】 Based on a frame-shear wall base-isolated structure, a finite element model is built for qualitative analysis considering the elastic-plastic model of isolation equipment and the elastic model of frame-shear wall. The research on the dynamic response of a frame-shear wall base-isolated structure is performed. The non-linear hysteretic property of isolation bearing meets the design requirement of bearing design. The acceleration response of the base isolated structure is decreased obviously by using the base isolation technology. The results show that the earthquake isolation and vibration reduction of the frame-shear wall base-isolated structure can achieve a good effect.更多还原
