One of the main components of water supply networks is fluid storage tanks, which are used to store, maintain, and supply the required water pressure. These tanks are very vulnerable to explosion and therefore one of the issues that is very important in the analysis and design of such structures is the issue of interaction between fluid and structure. The aim of this study was to investigate the ring stresses of reservoir walls due to blast waves and fluid hydrodynamic forces as well as water surface pressure due to the interaction of the structure with water. In order to achieve the above objectives, Abacus software has been used to simulate the numerical reservoirs of reinforced concrete cylinders under the impact of the explosion, taking into account the effects of water and structure interaction. For this simulation, three tanks with heights of 4, 6, and 8 meters and a constant radius of 3 meters were used, each of which was filled with water (empty, 25, 50, 75, and 100) from the depth of the tank with water. Is. The results of this study show that the above parameters affect the dynamic response of the reservoir structure so that the water surface pressure in the reservoirs is 50% higher than water and also ring stresses with the increasing water level, reducing the distance between materials. Explosion and reservoir elevation increase and hydrodynamic forces are more pronounced at close range.
