        abstract = {Seismic tremors, or earthquakes, can cause structural failures and casualties, impacting socio-economic stability, especially in areas with advanced developments. Elevated water tanks, common in urban areas, are particularly vulnerable to seismic damage. Base isolation, a proven technique for mitigating earthquake effects, can enhance the performance of such structures by reducing seismic energy transmission and shifting the structure's natural frequency away from dominant ground motion frequencies, thereby minimizing damage. The increasing urbanization has led to the widespread construction of elevated water tanks, which are highly susceptible to damage during seismic events. Earthquakes can significantly impact the structural integrity of these tanks, leading to potential failure and social-economic disruptions. To mitigate the seismic risks, Base Isolation is a proven technique that can effectively reduce the harmful effects of earthquakes on structures.
This study evaluates the performance of a double base isolated elevated water tank (Intze tank) under both far-field and near-field earthquake scenarios. In this design, isolators are installed both at the base and at the mid-stage of the staging, enhancing the tank's ability to withstand seismic forces. The seismic responses of the double base isolated tank are compared to those of a single base isolated tank (with an isolator only at the base) and a fixed base tank (without isolation). The results demonstrate the advantages of double base isolation in reducing seismic responses, thereby improving the structural performance of elevated water tanks during earthquakes.},
