In this paper, the seismic behavior of ground-supported cylindrical water tanks resting is investigated. The focus of the study is to identify the effect of soil structure interaction on the behavior of the water tank in response to seismic loading. For this purpose, circular tank resting on very dense soil is considered and the seismic response of tank under Northridge earthquake, 1994 was observed by performing the time history analysis. The response parameters are compared with idealized condition of tank with fixed base slab. The study infers that soil structure interaction significantly magnifies the response parameters such as radial displacement, hoop force, bending moment and base shear. The effect of water fill condition on the seismic response of the tank is examined byanalyzing two water fill conditions; full fill and half fill.
