中文摘要：
为研究阻尼器在框架核心筒结构中立面和平面布置差异对减震效果的影响,使用非线性软件PERFORM-3D结合框架核心筒结构的内力重分布机制,对4种阻尼器布置不同的方案输入3条地震波进行非线性动力时程分析,对比结构的最大层间位移角、最大层剪力、塑性损伤情况、结构总能量分配和滞回耗能在结构高度上的分配,从力、位移和能量的角度综合寻求阻尼器在框架核心筒结构中的最优布置方案.
英文摘要：
To evaluate the effects of a frame-core tube structure, finite element analysis software PERFORM-3D was used in the analysis. With the theory of transmission mechanism and the mechanism of redistribution of internal force, the dynamic nonlinear time-history analysis of a frame-core tube structure in the northwestern region of china was done. Other three schemes were compared considering the different arrangements of fluid dampers in flat and faqade surfaces. The maximum story drift, story shear force, plastic damage of the frame-core tube, energy distributionand bystcretic energy consumption in height were compared, and the best arrangement of fluid dampers were found in the frame-core tube structure.
