Analysis of Different Isolation for Liquid Storage Tanks

Abstract

One of the important structures, which is prone to damage is water tank. Due to increase in urbanization, there are large numbers of elevated water tanks which are constructed. Therefore to evaluate the performance of elevated water tanks under seismic load is primarily important. The present study deal with evaluating the performance of a double Base Isolated elevated water tank (intze tank) is evaluated under far field and near field earthquakes. For the double base isolated water tank, the isolators are installed at bottom of tank and in the mid-way of staging. To typify the performance of double base isolated water tank, its seismic responses were also compared with the case of single base isolated (isolator at the base only) and fixed base counter parts.
