Abstract Wateriskeptintanksthatareusedas storagebins.Projectsinvolvingthesupplyofwaterarecrucialforthe nation'ssocialandindustrialgrowth.Onemajornaturaldisasterthatcandisruptdailylifeforpeopleisanearthquake.Thisis because earthquakes harm infrastructureand area lifeline for all facilities.Elevated water tanks arecrucial forproviding drinking water and putting out fires since they do not collapse after an earthquake. If we look at the experience of a few earthquakesthathappenedinIndia,suchastheBhujearthquake(2001),wecanobservethatRCCwatertankselevatedwere more severely damaged, and some water tanks actually fell. The primary goal of this research is to measure the elevated reinforcedconcretewatertank'sperformanceunderdynamicload.Additionally,variationsindynamicreactions,includingbase shear,overturningmoment,displacement,andothers,werealsoexaminedinrelationtochangesinstagingheight,watertank capacity,seismiczone,andsoilconditions.KeyWords:watertank,Earthquake
