The applicability of available analytical formulations for elevated tanks with vertical stagings is shown to the similar tanks with battered stagings. The formulation includes the dynamic characteristics like lateral and torsional stiffness and natural periods. Both frame and shaft supported stagings for elevated tanks are considered with and without accounting for the effect of soil-structure interaction. The values obtained through analytical formulation are compared to the results of finite element analysis and found to have reasonable performance. Thus the study yields handy formulations to be used for seismic design of elevated tanks with battered stagings.
