Due to frequent earthquakes in recent years, the seismic safety of large storage tank is very important. In this paper, seismic response of large liquid storage tanks is analyzed. A model for liquid storage tank is established firstly. By modality analysis, dynamic behavior of large storage tank is obtained. After the model is excitated by seismic, seismic responses are obtained. The conclusions show that, without considering liquid-solid coupling, "elephant foot" buckling phenomenon doesn’t appear. This study provides reference for seismic design and seismic performance study of large storage tank.

In this paper, we investigate the free vibration and seismic response of a liquid storage thin cylindrical shell fixed on a rigid foundation including piping and attached structures which are considered as unaxisymmetric attached mass and stiffness. The coupled free vibration analysis method and seismic response analysis method are proposed when the thin cylindrical shell is coupled with a liquid contained in the shell, the attached mass due to the unaxisymmetric attached structures, and the attached stiffness due to the flexibility of piping. The equations of motion of the fixed-free cylindrical shell including a liquid, and with attached mass and stiffness are derived by the Flu¨gge’s shell theory analytically for a shell and the velocity potential theory for a liquid. Taking the dimensions of a shell, liquid and attached mass, stiffness as parameters, the free vibration and seismic response are investigated. Moreover, the comparison between the analytical results and the experimental ones is performed.

To large liquid storage tank, based on the potential flow theory, considering fluid-structure interaction, the potential-based elements and the shell elements are used to simulate the liquid and the tank, respectively. Using the displacement-velocity potential finite element method formulas, the seismic response analysis method of the liquid storage tank is obtained, and is implemented based on the ADINA program. Some useful conclusions of the tanks under the earthquake loadings are obtained through two examples, which provide the reference for the seismic design theory and the seismic performance, and provide the analysis approach for the damage behavior and loss assessment of liquid storage tank.
