The Effect of the Explosion during Fire on Steel Column Using Dynamic Explicit Method

Abstract
The explosion occurrence is the most likely events that may occur during a fire incident. This paper studies on nonlinear response of steel column against an explosion during fire event by using dynamic explicit finite element scheme. In this study, the effect of temperature of steel surface at the moment of explosion and scaled distance parameter are investigated. The results show that increasing temperature to more than 400 °C may cause large displacements and ultimately led to collapse the column. It is shown that increasing the temperature of the instant explosion for more intense explosions is less effective than explosions with larger scaled distance (Z).
