【摘要】 提出了核心筒部分悬挂结构体系,在已有该体系振动台试验基础上,建立了该体系的抗震分析简化力学模型及其理论公式。按小震、中震和大震3种不同的地震作用情况,分析了该结构体系力学模型和动力方程的差异。利用有限元分析程序SAP2000,对这种结构体系进行了小震和大震作用下的结构地震反应分析,计算结果与试验结果吻合较好。更多还原

【Abstract】 This paper puts forward core-tube partial suspension structure and sets up the simplified mechanic model and theoretical formulae of the structure on the basis of the shaking table experiment of the structure.The differences of mechanic model and dynamic equations were analyzed according to the different earthquakes that include frequent,moderate and strong earthquakes.The analysis of the earthquake responses of the kind of structure was carried out by SAP2000.The computational results fit well with that of the shaking table experiment of the structure.更多还原
