In this study, to investigate and analyze the seismic behavior of concrete in open rectangular water storage tanks in twodimensional and threedimensional spaces, the Finite Element Method has been used. Through this method, dynamic responses can be investigated together in fluid storages system. Soil behavior has been simulated using tanks boundary conditions in linear form. In this research, in addition to flexibility of wall, the effects of fluidstructure interaction on seismic response of tanks have been investigated to account for the effects of flexible foundation in linear boundary conditions form, and a dynamic response of rectangular tanks in twodimensional and threedimensional spaces using finite element method has been provided. The boundary conditions of both rigid and flexible walls in twodimensional finite element method have been considered to investigate the effect of wall flexibility on seismic response of fluid and storage system. Furthermore, threedimensional model of fluidstructure interaction issue together with wall flexibility has been analyzed under the three components of earthquake. The obtained results show that twodimensional model is also accurately near to the results of threedimension as well as flexibility of foundation leads to absorb received energy and relative reduction of responses.
