STATE OF THE ART OF INSULATED WATER STORAGE TANKS FOR POST-EARTHQUAKE EMERGENCIES

Guaranteeing the supply of water for human consumption immediately after a major earthquake is essential for the development of a resilient city.Unfortunately, in several cities around the world, this objective cannot be met due to the state of their distribution networks.One proposed solution is the use of isolated tanks for emergency response.This article presents an updated review of the state of the art of the seismic behavior of base-isolated water storage tanks.The topics reviewed were: studies on theoretical aspects of isolated water tanks, analytical and numerical analysis models used, experimental studies, among others.Finally, it is concluded that the introduction of isolators improves the dynamic response of the tanks; however, it is presented how several parameters affect this response.Aspects to be reviewed in future reports are also presented, in order to extend the research in this area.
