     axial stresses magnitude on the shell wall of steel tanks are one of the most important factors in health monitoring of these kinds of reservoir. controlling of the maximum amount of these factors can guarantee the safety of the tanks performance. as the objective of this paper to study aboveground tall cylindrical tanks, the finite element modeling (fem) strategy was used to simulate dynamic response of these systems. abaqus is used as the main finite element computer simulation software to make a nonlinear dynamic analysis. the simulated results visualize the distribution of axial stress of tanks shell under seismic loading.

    it is shown that for unanchored tall tanks the axial stresses amount in the case of using steel st52 is much less than using st37 which can be so important for structural designing.
