Seismic analysis of double-decker elevated water tank

Double-Decker Elevated Water tank is used for storage of large quantity of water. Direct source of water in water tank is from the rainfall. Taking water from tank for drinking, household & etc purpose is economical in that place where construction of well, bore well, etc is costly and area is less. Elevated water tanks are integrated part of lifeline facilities elevated water tank is storage container construction for the purpose of holding water supply. A large number of water tank is damage during past earthquake. So, there is need to focus on seismic safety. The aim of this paper to propose a seismic response of double-decker elevated water \tank in different zone and comparison with single elevated water tank. To study different types of load acting on it, bending moment an shear force and its displacement if any after seismic load is applied on water tank by using staad-pro software.
