Abstract Water tanks, particularly elevated ones, are critical structures that are essential for maintaining their intended functionality, even in the event of earthquakes. Consequently, there has been a growing interest among researchers in investigating the seismic performance of these tanks. While a considerable amount of research has been conducted on ground tanks, only a limited number of studies have focused on elevated tanks, and even fewer have specifically examined reinforced concrete elevated tanks. In this research, a reinforced concrete elevated water tank of 35 m3 capacity has been analysed on ETABS software, and the earthquake analysis is also carried out on ETABS software. During earthquake analysis of the model on ETABS software, it is first analysed as per Indian standard code IS 1893:2014 (Part 2), and then again as per European standard. During analysis, base moment, base shear, lateral force, story drift, story displacement, and axial force are analysed by Indian standard and Euro code, and then the results are compared. The result of the analysis showed a rise in storey drift, storey displacement, and lateral forces with an increasing zone factor for all soil types. The seismic response as per the European standard is similar to the response of the structure as per the Indian standard code. As per European standards, in soil type D, the seismic response values are higher as compared with type B and type C soils in both spectrum zones.
