“…This is due to the possibility of changing the technical parameters of the substrate made with bitumen, since an increase in temperature directly results in a change in its characteristics, and in extreme cases can lead to its plasticization. Violent, intensive rainfall corresponding to torrential downpours causes water intrusion into the foundation zone, which, when cyclic conditions occur, can result in the effect of leaching of soil from the bottom fringe zone [4]. Climatic influences cause cyclic thermal changes during many years of use, resulting in changes in the temperature of the stored medium in the tanks, as well as changes in the state of stress in the structural area.…”

Climate change introduces the need to look at new issues in the safe operation of engineering structures, [1, 2]. Analysis for the past decade has shown the significance of the weather changes taking place and the effects in the form of periodic long heat waves causing heating of external surfaces combined with solar radiation can cause significant structural impacts. Intense rainfall causing increased penetration of water into the ground also proves to be an important issue in terms of the proper condition of foundation zones. Performed studies have shown that in unfavorable conditions can lead to defects in the foundation zones of steel tanks.

“…In another study, two full-size reservoirs for buckling behavior under general and local differential settlement were investigated using the FEM software model with non-linear geometric algorithm. In these reservoirs, it was proved that local buckling occurs under general differential settlement in the wind girder and continues with a post-buckling behavior [18].…”

Liquid storage, particularly oil and petrochemical products which are considered hazardous liquid, are an important part of the oil industry. Thin-walled vertical cylindrical steel storage tanks are widely used in recent years. Due to high sensitivity of these structures in an earthquake and other external excitations may lead to catastrophic consequences. For instance, huge economic losses, environmental damages, and casualities, many studies have been done about these structures. past studies showed that liquid storage tanks, equipped with a floating roof, are potentially vulnerable while subjected to seismic loads and earthquake has been considered as one of the most destructive natural hazards. The reason is that such tanks are made of two separated parts (shell and roof) which each may have its own responses; sometimes causing resonance phenomenon and so that, roof movements, rooffluid interaction, roof-shell interaction, and also the way they are attached should still be investigated. Experimental tests of floating roof 's vertical fluctuation was performed in a full-scale reservoir tank and assessing of the results demonstrated that presence of a seal between floating roof and shell plate can significantly increase damping ratio in liquid sloshing and also suppress the roof`s vertical displacements. In other words, seal can control a floating roof and make it stop moving vertically over few cycles.

“…The calculations ignore both the geometrical and material imperfections of the structure, as well as other factors such as post-welding stresses [1]. The effect of the tank foundation settlement, which may lead to limit state exceedance should be also taken into account [2][3][4][5]. Due to the random nature of material parameters, probabilistic methods are commonly used.…”

The calculations of fuel tanks should take into account the geometric imperfections of the structure as well as the variability of the material parameters of the foundation. The deformation of the tank shell can have a significant impact on the limit state of the structure and its operating conditions. The paper presents a probabilistic analysis of a vertical-axis, floating-roof cylindrical shell of a tank with a capacity of 50000 m 3 placed on stratified soil with heterogeneous material parameters. The impact of a random subsoil description was estimated using the Point Estimated Method (PEM). In this way, the number of analyzed FEM models was significantly reduced. This approach also makes it possible to assess the sensitivity of tank settlement and deformation to the changing foundation conditions.
