SEISMIC ANALYSIS AND COMPARISON OF OVERHEAD INTZE WATER TANK, CIRCULAR WATER TANK AND RECTANGULAR WATER TANK AND RESPONSE SPECTRUM ANALYSIS

Elevated WTs are used to store water in the public water supply system and they play a significant role in the seismic areas. The flaw in WTs might be due to a lack of water or problem with people to suppress the flames during seismic activity. The seismic activity caused various breakdowns such as the breakdown Protection of ground and lack of support to the stages. The aim of this paper is a Reaction spectrum analysis, seismic analysis and comparison of overhead Intze WT, circular WT, and rectangular WTs with unfilled, ½ filled and complete in earthquake 3rd & 5th field is done by implementing in STAAD Pro V8i SS6. These three categories of high circular, rectangular & Intze WTs of 450000 liters capacity holds up on RCC frame stages height 27 m under seismic activity loads according to outline code section 2 of IS 1893:2002.
