Explicit Dynamic Analysis of a Steel Column Subjected to Near-Field Explosion

Bomb attacks inside or near buildings can cause Catastrophic damage to structures inside and outside the structure, collapse walls, blow up large sections of windows, and disrupt security systems. The casualties of the victims can be multiplied, including the direct effects of the explosion, the destruction of structures, and the impact of debris. Indirect effects can be combined to prevent a rapid evacuation, resulting in more casualties. In addition, the high loads due to chemical gas explosions can cause dynamic loads in many structures that are greater than the original design loads. In view of the threat of these extreme loading conditions, the behavior of the building structure under explosive charges is studied. A column under axial force and the blast load were simulated and analyzed. The ANSYS finite element platform is used to model columns with various support end conditions.
