Behavior of geogrid-reinforced concrete slabs subjected to contact explosions

Abstract

Bomb attacks are occurring in the world due to the increasing hot and cold wars. In this study, the contact explosion, which affects the resistance of the structure the most, was investigated among these attacks. Since the explosive is in contact with the surface of the structure in contact explosion, the reaction of the structure in bending and shear behavior due to sudden dynamic loading differs from other loads. In our experimental study, 50x50x15 cm reinforced concrete slabs reinforced with steel wire mesh, wire fence and geogrid building materials were produced in order to compare the behavior of concrete against explosion. In contact with these plates, 577gr explosive was applied and detonated. In the experiments, the contact explosion reactions of geogrid reinforced concrete and steel-reinforced concrete and unreinforced concrete were compared. As a result of the experiments, it was determined that the concrete reinforced with wire fence and geogrid is applicable against contact explosion.
