“…They observed that stresses and liquid sloshing heights in the tank increase with decreasing scaled distance of the explosive material and increasing aspect ratio, i.e. height to radius ratio [2]. In the figure 1 and 2 are seen deformation of tanks due to sloshing subjected the earthquake load.…”

Cylindrical steel tanks are widely used to store variety liquids such as water, petroleum, and industrial chemicals. They also have been becoming widespread for cooling in nuclear power plants last years. Steel liquid tanks can be exposed during earthquakes and also they can cause great financial and environmental damage with their containing petroleum or other hazardous chemical liquid. Explicit Dynamic tool in ANSYS Workbench reveals accurate results in dynamic analysis of structures under instantaneous and short forces. The Explicit Dynamic tool uses Eulerian Body with water to provide interaction between the water and the shell. El-Centro earthquake 0,22 seconds data was used as displacement force for to see the shear stress on the tank. The tank was covered with epoxy carbon material using the Workbench ACP tool to reduce shear stress.

“…Equation (14) also supposes that the impact load on the S i was absorbed and was completely changed into the initial kinetic energy of shell element S i and added liquid m 2 . Under such conditions, the absorbing energy can be expressed as equations (15) and (16), where E P2 represents the deformation energy of shell element S i :…”

“…Comparison between equations (13) and (15) reveals that if the shell elements move together with the added liquid mass, their deformation energy can be partly reduced compared to the empty condition; that is, E P2 < E P1 . e tank walls are composed of many shell elements.…”

Large steel storage tanks designed with long-span structures, employed for storing oil and fuel, have been widely used in many countries over the past twenty years. Most of these tanks are thin-walled cylindrical shells. Owing to the high risk of gas explosions and the resulting deaths, injuries, and economic losses, more thorough damage analyses of these large structures should be conducted. This study examines the structural response of a simplified steel storage tank under a blast impact, as calculated by the LS-DYNA software package. The numerical results are then compared with a scale-model experiment. On that basis, the simplified storage tank prototype, which has a 15 × 104 m3 capacity, is analyzed using numerical simulation. In this study, we address issues around the variation in structural responses—particularly of the failure mode, resultant displacement, structural energy, and dynamic strain under the impact. In addition, we also discuss the effects of varying the internal liquid level, constraint conditions, and blast intensity.
