AN EXPERIMENTAL STUDY ON STRUCTURAL FIRE BEHAVIOR OF REINFORCED CONCRETE WALL AFTER HIGH VELOCITY IMPACT OF HARD PROJECTILE

Abstract

Projectiles would be released by an accident such as damage of turbine blades, and impinge on structures. Flying objects such as airplanes are also possible to be impact projectiles. These accidents occasionally cause fire, if there are fire load such as oil, fuel and any other combustible materials. This research focuses on the structural fire behavior of load bearing reinforced concrete walls exposed to fire after high velocity impact of a hard projectile. Impact and fire experiments on small scale reinforced concrete walls were carried out. The results show the influence of local damage and the advantage of short fiber reinforced concrete against fire.
