Abstract

Past earthquake events have shown that even well-designed elevated water tanks can suffer severe damage or collapse. Much of this damage occurs due to a limited understanding of the behavior and appropriate selection of supporting systems during the design process. With a large mass concentrated at the top of slender supports, these tanks are especially vulnerable to horizontal seismic forces. Therefore, it is crucial to evaluate the strength and performance of these structures against such forces, particularly based on the seismic conditions of the region. The seismic performance of elevated water tanks for India’s critical seismic zone is presented in this report for a range of staging heights and sloping terrain, including zero, twenty, and thirty degrees. The Response Spectrum Method (RSM) in ETABS software is used to analyse a total of nine combinations while taking into account two mass idealization systems. The tank responses including base shear, storey displacement, shear forces, and bending moments in the columns have been analyzed to recommend the most suitable staging configuration for various earthquake zones across India. To suggest column diameter for particular zone considering cost parameter, optimization is also done for the best staging configuration. As per IIT Kanpur and Gujrat state disaster management authority guidelines, critical direction of seismic forces is considered and quantity of steel and concrete required is obtained. Results show that on zero slope ground all parameters will perform better during seismic events for all seismic zones.
