A three-dimensional and elastic-plastic dynamic buckling analysis method that takes into consideration fluid-structure coupling and large deformation is proposed in order to accurately simulate the seismic response of cylindrical liquid storage tanks. The results of a dynamic buckling experiment of a tank using seismic motions closely match those of numerical simulation by the proposed method. The mesh size of the analytical model greatly influences the buckling analysis results. Optimization of the size is also discussed.
