The considered isolation systems are high damping rubber-bearing (HDRB), lead-rubber bearing (LRB) and friction pendulum bearing (FPB). In order to measure the effectiveness of the isolation systems, the earthquake response of isolated containers is also compared with non-isolated tanks considering bi-directional excitation. An equivalent mechanical model of rectangular containers which has six degrees of freedom and contains three lumped masses known as basic mass, flexible mass and convective mass is used. Results of this study show that seismic base isolation can be an effective way to reduce seismic responses, such as base shear and hydrodynamic pressure. However, the inclusion of base isolators is found to increase the sloshing height. An increase in displacements for all isolation systems in horizontally isolated tanks seems to be inevitable. It is also found that the seismic response of isolated tanks is not very sensitive to the interaction effect of the bearing forces. A careful selection of isolators, with appropriate mechanical properties is needed for the optimal seismic isolation design of rectangular containers.
