As the terrorist attacks are repeated continuously all around the world. They target the public building for terrorism because their large amount of people is there. The use of a large amount of explosive material that collapses the building component. In previous study analyses the multistory building and frame with different loading and structural configuration. Using different software such as ETABS, SAP2000, ANYSIS, and ABAQUS. Using the Finite element method for time history analysis during the blast. To know the performance of the building of frame using X- plate, Damper, Shear wall, and different Bracing. In this paper focus on understanding the behavior of the reinforced concrete structure under blast load at different standoff distances with different charge weight. TNT is used for explosive material. And study on displacement, storey drift, deflection fundamental frequencies, and stress on structural members. Future studies will be staggered shear wall with different bracing and different blast load and load distances.
