摘要
利用豪斯纳理论对贮油罐罐内的液体作了近似处理 ,按有限元法考虑了回转壳的刚度阵及质量阵与贮油罐中液体的刚度阵及质量阵的组合 ,在此基础上重点分析了贮油罐的地震局部动力效应 ,即单元上连续质量惯性力的影响 ,对地震波激励下贮油罐的动力响应作了有限元分析 ,获得了一些有意义的计算结果 。
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.
