The effect of seismic isolation on dynamic response of such tanks is investigated by performing finite element (FE) time-history analyses on various models. The proposed FE method is capable of simulating the accurate threedimensional behaviour of the isolated tanks involving the nonlinear hysteretic behaviour of seismic isolators. Through this study, the effects of different parameters on the effectiveness of the seismic isolation system are investigated. The examined parameters include: lateral versus vertical isolation, locations of isolators, shaft stiffness, and tank aspect ratio. It is concluded that the application of passive control devices to conical elevated water tanks could offer a substantial benefit for the earthquake-resistant design of such structures. The obtained results further show that the magnitude and distribution of seismically induced forces, moments and displacements could be controlled through appropriate selection of device properties, isolators’ locations, and tank’s structural and geometrical characteristics.
