Reviewing Various Methods of Seismic Analysis of Aerial Tanks, Considering Interactive Effect of Fluid,

In the seismic design of tanks, though the added mass model is used to determine basic cutting and collapse moment, the added mass model with the sloshing mass are utilized formore accurate and appropriate modeling, taking advantage of limited component methods. Moreover, in many seismic analysis processes, these kinds of structures, regardless of interaction of soil and structure and including the fixed basis hypothesis, whereas in regard to the height and mass of the structure and, considering this interaction, will have considerable effect on the achieved results, especially when the basis soil is of soft and flexible one. Hence, this essay is primarily intended to review various methods of seismic analysis of aerial tanks.
