Investigate the behavior reinforced concrete frames loads against blast

Due to the terrorist attacks in the world and also the important role Buildings Resistance against possible threats from The bombing in the vicinity of buildings, building performance review Contribute to resistance against blast loads such Buildings against any threat of the bomb. In this paper, the behavior of reinforced concrete frames under load paid explosion. For this purpose a 4-storey building under gravity loads and different values of the explosion to a distance of 5 meters from the ABAQUS finite element model of the structure by the software. The following structures are analyzed for different values of strength and values of the force-displacement movement in various states of explosive and studied the resistance of concrete. The results show that the magnitude of the explosion increases with increasing load. As well as by increasing the strength of the reduced displacement and force values increase.
