Abstract: “Analysis of Reinforced Concrete Structures subjected to blast loads in the commercial domain has gained importance due the frequency in which such buildings and structures are being targeted by the terrorists which not only causes serious damage to the struc tures but also has resulted in loss of precious hu man life . Though the potential targets and the damages it causes to the structures may be difficult to predict, it is important to consider the blast load in addition to the conventional loads considered in the analysis and design of buildings to minimize the damage caused either due to manmade or accidental blasts. A study is undertaken to compare the effect of inclusion of steel fibers of varying percentages, when subj ected to blast loads at different standoff distance s of 3m, 6m and 9m by varying the ch arge weights when compared to the reinforced concrete with M25 grade at the same standoff distances and charge weights . The variations of the high strain s and the lateral de”
