Abstarct: The placement of surface structures, such as fixed and movable against various loads such as war and terrorist threats, such as explosives or explosion of fuel lines such as oil and gas, in close proximity to these structures, results in the formation of a level of tensions with an almost oscillating nature in the constituent material will be. In some cases, these structures are like reservoirs containing stored materials, including fuel and refinery, and sometimes also water carriers that will be used to combat combustion. In any case, environmental considerations, conditions of use and even financial value are very important for the stability of these structures against different loads. The importance of this is the main reason for choosing the topic of this thesis. This thesis examines the effect of explosive explosive loading on reservoirs. To do this, we used Adobe Autodyn's finite element software to simulate the problem. We used SPH solver for modeling and analyzed the effect of explosion in different situations. These loads were carried out on two types of steel and concrete reservoirs. Explosive materials with three different masses of 500, 1000 and 2000 kilograms were placed at a distance of 10, 15 and 20 meters from the reservoir on the ground. In order to record the explosion parameters, six measurements were carried out in different sections of the reservoir and finally the results of the measurements recorded in the measurements were compared. The most important result is the increase in the effect of explosive loading with the increase of explosive mass and in comparison with the decrease in the effect of increasing the distance from the explosion point on different sections of the reservoirs.
