Structural Analysis of Asymmetrical Multistory Building with Watertank Act as a Seismicdamper

Abstract

Overhead water tank commonly used in buildings for various requirements. Overhead water tank is not only for water supply which also control the displacement of building during the earthquake force acting on structure. RCC over head water tank which gives the certain mass to the building this mass reduce the lateral movement of the building during seismic force on structure. In multi story structure, water tank also will lead the important factor for reducing the seismic response of the building. Using this technique overhead water tank placed on asymmetrical multi story building at different places. In thatone particular location reduce the seismic response more that place is choose for placing water tank. The advantage of this method isoverhead water tank is used for water supply as well as controlling of seismic response. Response spectrum analysis are used for analysis the structure in ETABS software. This software is used to checking the particular location for fixing the overhead water tank.IS standards are used for this analysis. In this experiment purpose the G+10 building is analysed in this study. This method is very economical it save the extra money for strengthening the building.
