The increased number of terrorist attacks mostly in the last few years has shown that the effect of blast loads on buildings is a serious matter which we should be considered during design process of buildings. Although these kinds of terrorist attacks are exceptional cases, man-made disasters; dynamic loads i.e. blast loads are really need to be carefully calculated just like earthquake and wind loads. The investigation of behavior of Ferrocement composites and Steel Fibre Reinforced Concrete composites under blast loading is presented in this paper. Individual ferrocement panels and Steel Fibre Reinforced Concrete panels are tested analytically under blast load, and the behavior against blast loading is then studied.
