Abstract (EN): The current paper presents an investigation into the parametric study of the dynamic buckling behaviour of empty cylindrical steel tanks of different heights, radius and wall thickness, anchored at the bottom and with an open top. The study attempts to estimate the critical load (Pcr), which induces the elastic buckling at the top of the cylindrical shell under a suddenly applied concentrated load with infinite duration in the horizontal direction through transient dynamics analysis (including geometric non-linearity) using the finite element analysis commercial software ANSYS, while applying the criterion of Budiansky-Roth and checking the plan-phase, and subsequently obtain the stabilization level of the critical buckling load versus the geometric characteristics of the tanks in question which leads to their design. The investigation showed that the studied parameters have a pronounced effect on the buckling load of the tanks and the results are discussed in this study.
