In a view of increasing vehicular bomb explosion of any kind, nearby buildings results in dynamic loads, which may be greater than originally designed loads. However, accidental events such as explosions in storage facilities, gas explosions, or explosion at quarries also occur from time to time. An explosion may lead to catastrophic damage on the buildings’ external and internal frames depending on the occurrence of the blast (within or immediately nearby buildings). Hence efforts have been made during the last few years for developing the analysis and design of blast resistant structure. Hence for adequacy of blast loading, IS 4991-1968 is used for calculating scaled distances. The studies were conducted on the behaviour of columns subjected to blast loads using Carbon Fibre Reinforced polymer wraps. The column of size 300 mm X 300 mm with 3000 mm long, and 25 mm diameter longitudinal bars of 8 numbers along with 10 mm diameter transverse bars has been considered in the study. The LS-Dyna software tool has been used to evaluate the outcomes of Carbon Fiber Reinforced Polymer (CFRP) wraps on columns performance of the building towards the explosion. It is found that increasing the number of layers of CFRP wraps increase the shear resistance beneath blast load. The CFRP wraps confirmed more resistance to blasting by decreasing the cracks, deflection, and also surface damage of column.
