Abstract

Water is the lifeline of humankind. During the earthquakes their safety and functionality is of major concern. Elevated water tanks consist of huge water mass stored in a tank at the top and is supported by a slender staging system, which is of critical significance contributing towards the failure of the tank during earthquakes. Due to the dynamics of fluid structure interaction, the seismic behavior of elevated water tanks is a complex phenomenon to understand.

In the present study, the seismic performance of intze type of elevated water tanks with various heights of the cylindrical portion for same storage capacity are considered. Seismic analysis is performed considering the elevated water tank as a two degree of freedom system. Different water levels in the tank are studied and the responses such as time periods, sloshing wave heights, base shear and overturning moments are investigated, compared and presented.

Keywords

Fluid Structure Interaction, Convective Mass, Impulsive Mass, Base Shear, Base Moment, Sloshing Wave.
