earthquake. By analyzing & designing, the structure will withstand collapsing due to the lateral loads. So respective cases taken and fixed focused upon the seismic actions of the elevated water storage tanks by considering the past earthquake records to design the structure in view of safety and durability (Livaoglu and Dogangun 2006 [1] Dogangun and Livaoglu 2007 [2]; Santhosh, Vangaveti Sai, Susanta Kumar Sethy, and A.

Compared to the trenches, the elevated water storage tanks give a better response to the seismic behavior by resisting the later loads that occurred due to earthquakes.
overhead tanks are extremely weak under adjacent forces due to an earthquake zone. In the past earthquakes, it has ensued found that the reinforced concrete elevated overhead tanks under lateral earthquake loads were suspectable where in some cases the structure has experienced collapse. Whereas the water works as an important role in the dayto-day life of a human being the elevated tanks should be designed as per the code provisions so that to avoid the failures of the structure and for the life of the structure. The study and creation of the elevated overhead tanks are done in ETABS software according to Indian Standards Codes. The reinforced concrete elevated water storage tank and the steel elevated water storage tanks have been designed for a full tank condition and the response spectrum plots and the time-history plots are also generated along with displacements & drifts. The columns and beams of the reinforced concrete storage tank are designed in accordance with IS456:2000 and the steel water tank is designed in accordance with IS800:2007. The designed structure is analyzed to check the reaction of the structure under the seismic events and the time history analysis is also being analyzed from the previous records.

Key Words: ETABS, Elevated Over-Head Water Tanks,
The structural analysis modes are categorized into five classifications they are –
Reinforced concrete & Steel Elevated Over-Head Water Tank, Response Spectrum, Time -History Analysis.
1. INTRODUCTION The elevated water storage tank remains built which is used for the storage and distribution of the water to the villages, towns & cities because the water is the most crucial part of human life and the trenches are used to stock the drinking water are out of shortage and the elevated tanks are built for storing and distributing the water. In the construction of these tanks, it has been very easy to store and distribute the water but after the structure is exposed to the natural calamities such as earthquakes and others calamities and after the structure is exposed to these and it has started to collapse due to lack of resistance towards lateral loads. So, by analyzing and designing the structure for resistance to the lateral

2.1 EQUIVALENT STATIC ANALYSIS The analysis performed upon the structure resembling the impact of seismic activity motions is usually defined with a response spectrum. This one assumes that the structure reacts around its primary modes and it's true that the construction has to be low-rise in addition to it should not twist ominously when the ground moves.
