【Abstract】 After liquid in oil tank was approximately treated on basis of Housner’s theory, the finite element method is used to derive the mass matrix and stiffness matrix of the revolutionary shell. Then these matrices are combined to the mass matrix and stiffness matrix of the liquid in the tank. The seismic local dynamic effect of the storage tank has been emphatically analyzed on the base, and the continuous mass inertial force in the element is considered. A finite_element analysis was proceeded for dynamic response of oil tank under the action of seismic wave excitation. Some significative results of calculating were obtained. These results had definite reference value for design of oil tank.更多还原
