Abstract: Water, a vital resource for sustaining life, requires proper storage. Elevated water tanks are constructed to serve this purpose. These tanks must operate reliably, even during and after earthquakes. Analysing the hydrodynamic behaviour of elevated water tanks is challenging due to the complex fluid-structure-soil interaction involved. The interaction between the tank and the surrounding soil structure, influenced by soil properties such as elasticity, cohesion, and angle of friction, significantly impacts the tank's performance. This paper presents recent studies focused on modelling the fluid-structure-soil interaction analysis of elevated water tanks. The objective of this study is to provide an overview of the fluid-structure-soil interaction concept for the analysis of elevated water tanks. A systematic literature review was conducted to select and categorise publications that include experimental and analytical studies on fluid-structure interaction, soil-structure interaction, and fluid-structure-soil interaction.

Keywords: elevated water tanks; EWTs; fluid-structure interaction; FSI; soil-structure interaction; SSI; fluid-structure-soil interaction.
