摘要考虑不同土-结构相互作用(SSI),对核电站安全壳结构进行动力响应分析的程序很多,它们采用的分析方法各不相同,如地下结构基础分析法程序CLASSI、等效线性有限元程序FLUSH、非线性有限元分析程序DYNA3D。使用这3种程序简单分析了安全壳结构的动力响应,给出了动力响应分析结果。讨论了以上3种程序在进行SSI分析时的可靠性,比较了它们在峰值加速度和响应谱作用下的响应。 At present, there are many procedures that are used to analyze dynamic response of the nuclear power station structures. In these procedures, analytic methods are different. For example, CLASSI uses the substructure method, FLUSH uses the equivalent linear finite element approach, and DYNA3D is a nonlinear finite element procedure. Considering the soil-structure and structure-structure interaction, the three well-rounded procedures are used to analyze dynamic response of the containment shell of nuclear power station, and linear results are compared with nonlinear results in this paper. The uncertainties in analyzing a soil-structure system due to SSI analysis procedures are also discussed.
