Based on the importance of explosion of the specific structures with composite steel shear wall and concrete-filled steel box columns (CFT), this study investigates the effect of explosion on such a structures. An 8-story steel structure with steel shear wall as a lateral resisting system and CFT columns was designed, then was modeled under blast loading in the air. This study presents that by addition of two concrete layers to the composite shear wall, with respect to the case with one layer, considering the constant amount and distance of the explosive material TNT from the structure the average out-of-plane displacement of the shear plate is decreased by 63% and also the type of damage has changed from the failure of the shear plate to buckling of the shear plate. As well the stress concentration is transferred from the plate and boundary elements connection to the center of the plate and the absorbed energy has increased by 380%.
