摘　　要：对固、液耦合储油罐的地震局部动力效应,按有限元法考虑了回转壳的刚度阵及质量阵与容器中液体的刚度阵及质量阵的组合,推导了回转壳单元局部动力效应公式,并编制了计算程序。通过对储油罐的节点动位移、动内力的计算,发现储油罐的局部动力效应正比于节点加速度和单元连续质量;由于附连体质量的影响,储油罐的局部动力效应更为显著,这对工程设计是非常有益的。The finite element method is used for deriving the mass matrix and stiffness matrix of the rotatory shell, then these matrixes are combined with the mass matrix and stiffness matrix of the liquid in the tank, on this basis, the local dynamic effect formula of rotatory shell element is deduced and the calculating procedure is worked out. By considering the continuous mass inertial force in the element and calculating the nodal dynamic displacement and dynamic inner force, it could be found that the local dynamic effect of reserve tank is directly proportional to nodal acceleration and continuous mass of unit and the local dynamic effect of reserve tank is more obvious owing to attached-object. These are beneficial to engineering design.
