Abstract :Construction, mining, oil, forestry, and agriculture all use blasting processes both in our country and in the world. A wide range of civil engineering projects, including homes, roads, railroads, dams, and airports, use blasting technology. The blasting process provides some advantages, but it also has drawbacks. Blasting has negative impacts, such as air shock and ground motion. This investigation concentrated solely on ground motion induced by an explosion. Utilizing the well-known MATLAB programming language, BlastGM software was implemented to obtain ground motion acceleration-time information. This software uses the maximum acceleration value and the ground motion acceleration time envelope curve to determine the acceleration-time changes of blasting-induced ground motions. Furthermore, this software uses the ground motion acceleration-time values to determine the shock\\\'s reaction spectrum. This study looked at how a recessed reinforced concrete (RC) rectangular water tank was affected by ground motion based on blasting. In Turkey, these tanks are built very frequently. For these tanks, the impact of ground motion brought on by blasting is crucial. ANSYS software produced the recessed RC rectangular water tank\\\'s three dimensional (3D) finite element model (FEM). Furthermore, the recessed RC rectangular water tank\\\'s maximum stresses and displacements were examined. The study\\\'s findings demonstrate that the recessed RC rectangular water tank is greatly impacted by blast-induced ground motion.
