Abstract:

针对高层框架-剪力墙基础隔震结构,考虑框架与剪力墙之间的相互作用,建立了高层框架-剪力墙基础隔震结构的动力分析模型,剪力墙为分布参数体系,框架结构为集中参数体系,通过边界条件把隔震支座及框架-剪力墙结构中框架部分对剪力墙的影响引入到分布参数体系,推导出高层框架-剪力基础隔震结构的频率方程及振型正交条件,进一步应用Hamilton原理,推导出隔震层隔震装置作用在各振型上的等效阻尼比,从而实现该体系运动方程的解耦,然后通过振型叠加法求解结构的地震响应。通过对一栋10层框架-剪力墙基础隔震结构进行动力特性及地震响应仿真分析,结果显示,建立的动力分析模型能较好的反映结构的动力特性,提出的高层框架-剪力墙隔震结构动力求解新方法能方便的求解结构的动力响应,与有限元数值积分法基本一致,可以反映地震作用下框架与剪力墙相互作用的经历。
