Seismic and Wind Load Comparative Analysis of Overhead Intake Water Tanks with Unfilled, Half Filled and Completely Filled Condition in Earthquake III to V-Zone

Safe and pure water is most important elements for human being to prolong healthy life. Reinforced cement concrete overhead water tanks are largely used to offer safe drinking water. There are several water supplying systems having in developing countries, like India, where population is increasing on daily basis, that's why there is necessary to construct large amount of water tanks. Previous designs of water tank completed by working stress method given in IS: 3370 1965. From past records we can say that, many of reinforced concrete elevated water tanks were severely damaged or collapsed during the earthquakes and cyclones all over the world. Generally, these are happening because of the failure of supporting system which states that the supporting system of the elevated tanks has more serious significance than the other structural parts of tanks. Mostly the damages observed due to the seismic events and cyclonic events. This happens might be because of the lack of knowledge regarding the proper behaviour of supporting system of the tank against dynamic effect and also due to inappropriate geometrical selection of staging patterns. In order to require proper head of water, its generally require to construct elevated water tank, generally these types of water tank is used for storing water for fulfil daily needs. For storing water R.C.C. structure is most favourable structures amongst others structure. Elevated Water Tanks is widely used for storage large amount of water for supply system and its play vital role in seismic areas. Water Tanks may be flaw because of scarcity of water or problem with the peoples to suppress the flames during seismic movement. The seismic movement is responsible for different failure such as ground surface failure and deficiency of support to the stages. The aim of this Research work is Response spectrum analysis, seismic analysis of overhead Intze Water Tanks with unfilled, half filled and completely filled condition in earthquake 3rd to 5th Zone. This whole analysis is done by STAAD Pro V8i SS6. The seismic zones of Zone-III, Zone-IV, Zone-V and the equivalent lateral load characteristics have been taken from IS 1893 (PART 1)-2002 & draft code IS 1893 (Part 2) and IS 875 (PART 3) - 1987. For this different condition of water tank. It has Intze shape. Water Tank having 1800000 litres holding capacity and supported on RCC frame stages height 20 m & 30 m under seismic movement loads provide according to code section 2 of IS 1893:2002.
