【摘要】 本文按有限元法导出了回转壳的刚度阵和质量阵，并用有限元法与源汇法 相结合的方法导出了该容器中液体的刚度阵（重力引起的）与质量阵，把它们 相应地加在一起就可用于对贮液罐作水弹性抗震分析。同时，对文中两个具有 柱支承的贮液罐，因其在水平地震时其周向主要呈ｃｏｓθ变形，于是，可利用 “子结构”的概念来处理当回转壳轴对称性被破坏时所出现的富氏系数耦联问 题。最后，为了使贮液罐抗震分析得到简化，本文又在上面计算分析的基础 上，按梁变形理论对文中列举的三个具体算例进行了抗震分析。从而为一些较 复杂的水中工程结构的抗震分析提供了近似计算方法。 文后列举了三个算例的频率实测结果。更多还原

【Abstract】 In this paper, the finite element technique is used to construct the mass and stiffness matrices of the revolutionary shell,and the finite elem- ent procedure is used in conjunction with a simple source distribution on all surfaces of a liquid, which is contained in the rovolutionary shell, to drive the expressions for the mass and stiffness(because of the gravity) matrices of the liquid. Once they are obtained, they can be combined with those of that shell in order to analysis the earthquake hydroelastic respo- nse of the liquid storage tanks. Two examples of the revolutionary liquid storage tanks supported by columms was discussed. Due to the circum ferential. deformation of the tank, caused by horizontal earthquake, is of the cosine type, we may use the concept of "substructure" to deal with the couple problem of the Fourian coefficient when the axissymmetry of the revolutionary shell was destroyed. At last, in order to simplify the earthquake response analysis of the tank, based on the calculation above, the anti-earthquake evaluation on three examples are illustrated with the beam deformation theory, and then the approximate method to dea1 with the more complex problem for the structure in water is presented. Along with it the actual measured results of that three calculated examples are descriped.更多还原
