For the seismic analysis, tanks were considered to have a linear elastic behavior, the tank-water interaction was represented by an equivalent mechanical model, and the hysteretic behavior of the isolation system was represented by a bi-axial hysteretic restoring force model. The parameters of this study are: the water-height/tank-inner-radius ratio, the tank-wall-thickness/tank-inner-radius ratio, the target vibration period of the isolation system, and the friction coefficient of the isolation system. Twenty-one pairs of selected and scaled ground motions were used in time-history analysis of the case studies. The objective of this analysis was to study the effect of bidirectional ground motion as well as the effects of study parameters on seismic response of base-isolated RC water storage tanks. Seismic responses of base-isolated systems, when compared to fixed-base systems, show an effectiveness of FPS isolation system in the reduction of base shear values in the order of 71% to 92% for H/R = 0.5; of 84% to 97% for H/R =
