Due to the recent increase in various terrorist activities all over the world, the safety of the structures should be designed to resist bomb blasts. Blast loads are basically dynamic loads of a type that needs to be attentively calculated like wind and seismic loads and the structures should be designed by considering them to make it blast resistant. The behavior of Steel Fibre Reinforced Concrete (SFRC) under the condition of blast loading is presented in this paper. The panel of 50mm thickness is taken into consideration. The effect of varying the aspect ratio of fibres in the fibre reinforced concrete is studied.
