An investigation of Fluid level effects on the seismic behavior of anchored tall steel aboveground tanks

Fluid level effects on the seismic behavior of storage tank are one of the most demand in the performance monitoring of tanks. Sloshing phenomenon in these kind of vessel isconsiderable in the sense of creation of axial and hoop stresses. As the objective of this paper is to study the relationship between the fluid height and the seismic behavior of these structures, the Finite Element Modeling (FEM) strategy was used to simulate dynamicresponse of the liquid tank system and so the Abaqus is used as the main finite element computer simulation software to make a nonlinear dynamic analysis. It seems that in thetall anchored tanks controlling the fluid level in the state of empty and half-full is not required
