Seismic Performance of RC Elevated Water Tank – State of Art Literature Review (original) (raw)

—In the 21st Century, with the expansion of cities, it is required to store and distribute water to areas far away from water reservoirs. RC elevated water tank is a feasible alternate for distributing water under natural head to the maximum possible area. It is very important for water tank to remain in function later to any natural calamity like earthquake. Seismic behaviour of them has to be investigated in depth. Historically, tank damage during earthquake occurs due to contribution of base shear, over turning moment, transverse displacement and sloshing displacement. Therefore, the estimation of the structural response to lateral forces has to be mainly investigated and elevated tank is to be designed accordingly. The reviewed literature shows different aspect for seismic behaviour of RC elevated water tank.
