摘　　要：针对核筒悬挂结构,建立了三维有限元模型,并且考虑材料非线性,在耦合地震的作用下,进行了弹塑性时程分析,得到了结构不同部位各节点的响应。将结果与单维地震作用下的结构响应进行比较,总结了耦合地震作用下悬挂结构响应的规律,对悬挂结构进一步的抗震研究和设计提供参考。In this paper, a three-dimensional finite element model of the core-tube suspended struc- ture is established. The modal analysis is conducted and the elastic-plastic time history analysis under the coupled earthquake is conducted afterwards, with the material nonlinearity been considered. Therefore, the responses of each node in different parts of the structure are obtained. The results are compared with those under the single-dimensional seismic waves. The laws of the suspended structure responses under coupled earthquakes are summed up and they can be a reference value to further seismic research and design of the suspended structure.
