Elevated water tanks are liquid storage structures that are vulnerable to lateral seismic loads, the analysis of these structures when subjected to seismic loads is critical. The present study involves the dynamic analysis of liquid storage tanks using finite element software ETABS. In this study, the seismic behavior of various liquid storage tanks is investigated by performing a dynamic response spectrum analysis with FEM-based software (ETABS). Elevated tanks of various shapes (circular, rectangular, and square) and staging patterns (cross-staging and normal staging patterns) with similar capacities are analyzed in this study. The findings of this study include an estimation of the Maximum story displacement, maximum story drift, and maximum base shear have all been compared for different shapes and staging patterns of tanks. The results of the parametric study show that the cross-staging tanks are more efficient than normal staging tanks when subjected to seismic loads, and rectangular tanks show the least story displacement and story drift among the three shapes of the tank. This paper presents the dynamic analysis of liquid storage tanks of various shapes (circular, rectangular, and square), and staging patterns (cross staging and normal staging patterns) with similar capacities are analyzed using finite element software ETABS.
