摘要
按有限元法考虑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 ,在此基础上重点分析储液罐的地震局部动力效应 ,考虑单元上连续质量惯性力的影响 ,通过对工程实例的计算 。
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 is emphatically analyzed on the base, and the continuous mass inertial force in the element is considered. It can be found from the engineering case calculation that the local dynamic effect must be considered when the anti-seismic analysis of the storage tank is carried out.
