Three tank sizes were selected to represent different height to radius ratios. All tanks are anchored on concrete ring-wall foundations. Nine earthquake time history records were used to develop response spectrums as input for design level ground motion. A combined fluid-structure finite element model was developed for each of the tank geometries. The computer models were run using linear elastic and nonlinear inelastic model property assumptions. Results of this study show the substantial variation of values in base shear and overturning moment depending on the seismic inputs and modeling assumptions used. The ratios of base shear between linear elastic and nonlinear properties ranged from 1.0 to 3.1, and overturning moment values ranged from 1.0 to 3.0, which are mostly smaller or equal to the design standard reduction R-factored value of 3.0 for anchored tanks.
