Study of wall thickness interaction with fluid wave height on aboveground cylindrical steel tanks under earthquake

Seismic performance of storage tanks as one of the main lifeline elements has attracted the interestof many researchers. Sloshing phenomenon in these kind of tanks is considerable in the sense of creationof axial and hoop stresses in the tank’s wall. The study of wall thickness effect on sloshing response ofaboveground cylindrical steel tanks under the seismic load under earthquake is the principal purpose ofthis research. The Finite Element Modeling (FEM) method is applied to simulate dynamic response andsloshing phenomenon. Abaqus is used as the main finite element simulation software to make a nonlineardynamic analysis. The obtained results revealed that in anchored wide tanks the wave height value in thecase of variable thickness is much higher than the case of constant.
