     as known from some very upsetting experiences, liquid storage tanks collapsed or were heavily damaged during earthquakes all over the world. for this reason, numerous studies have been done on the dynamic analysis of fluid containers; a few of which have been studied on the seismic responses of flexible rectangular tanks with base isolation. this paper focuses on analyzing, the results and arguments about the design of seismic base isolated flexible rectangular tanks. the mechanical model used in this paper contains three masses known as: sloshing mass, rigid mass and flexible mass. lead rubber bearings (lrb) and friction pendulum systems (fps) are two types of seismic isolators, used to isolate the storage tank base. results show that seismic base isolation can be an efficient way to reduce dynamic responses such as base shear and hydrodynamic pressure, but it can adversely affect the sloshing height and the relative displacement of the structure to the ground.
