摘要：Water tanks are one of the most important lifeline structures. In most of the cities and rural areas, watertanks forms an integral part of water supply scheme. The liquid storage tanks possess low ductility and energyabsorbing capacity as compared to the conventional buildings. So seismic safety of liquid storage tanks is ofconsiderable importance. The water tanks get heavily damaged or collapsed during earthquake due to the fluid-structureinteractions, hence the seismic behaviour of tanks has the characteristics of complex phenomena. Water storage tanksshould remain functional in the post earthquake period to ensure potable water supply to earthquake affected regions.The main aim of this study is dynamic analysis of different types of RCC water tanks. Ground supported rectangularand circular water tanks, over head circular and rectangular water tanks are considered. Housner’s two mass model forwater tank is selected for dynamic analysis where the whole mass of water is divided in to two, impulsive liquid massand convective liquid mass. Analysis is carried out to find the base shear and base moment. The manual dynamicanalysis is done with varying height of water level in the tank using IS 1893 (Part 2) guide lines and study the effectsdue to change in height of water level. The manual dynamic analysis is compared with dynamic analysis performed inFEM software ETABS for varying height of water level.
