Analysis of seismic response of liquid-storage elevated tank involving fluid sloshing and the uplift of tank bottom

In the seismic response analysis of storage liquid tank of supported-ground,there is not a simple and effective model in the forepassed research,which simulates the 3-D seismic response of liquid storage tanks,nonlinear factors such as multi-mobile boundary of shell and fluid and large geometric deformation.In this paper,several finite-element models have been built by the elements of the general finite-element procedure ANSYS.The analysis of the seismic response of storage liquid tank,which includes the anchored tank and unanchored tank,has been conducted.By comparing the numerical analysis with the experimental results of Clough,the ANSYS model is proved to be feasible and effective.The bottom of liquid storage tank uplift and sloshing of liquid can be reproduced by computational analysis successfully.The research provides the reference to the static and seismic analysis of liquid storage tank.
