摘　　要：摇摆结构放松了结构与基础间的约束或构件间的约束,这些连接处只受压而不受拉,在地震作用下发生摇摆而其本身又不产生弯曲变形。摇摆降低了地震作用和结构本身的延性设计需求,减小了地震破坏,节约了结构造价。论文提出一种新型摇摆结构,即在传统摇摆结构上安装黏滞阻尼器,研究该结构在地震作用下的反应特点与减震效果。通过与摇摆框架的地震响应分析对比,表明安装黏滞阻尼器的摇摆框架能大幅度提高结构的抗震性能,降低地震带来的危害。The rocking structure relaxes the constraints between the structure and the foundation or between the members.There is only pressure without tension at these joints which sway during earthquake without bending deformation.Rocking reduces the impact of earthquake and the ductility design demand of the structure itself,reduces the earthquake damage and saves the structure cost.A new type of rocking structure-the traditional rocking structure equipped with viscous dampers-is proposed,and its response characteristics and damping effect under earthquake action are studied.Compared with the seismic response analysis of the traditional rocking frame,it is found that the rocking frame equipped with viscous dampers can greatly improve the seismic resistance of the structure and reduce the damage caused by earthquake.
