Behaviour analysis of building column structure with retaining wall due to explosion load in front and side a construction

Analysis of the impact of explosion loads on buildings to determine the structural column reaction conditions as a result of the blast loads. The model building structure is a three-story structure with a height of 10.5 meters. At distances between 10 and 15 meters from the source of the blast, the analysed explosive weight of 500 kg TNT was converted to a static load. SAP2000 software was used to conduct the analysis. The analyses’ results in the form of a moment force that compares a building’s column structure’s response. Based on this analysis, it can be concluded that the conditions in the structure without restrained walls are insufficient to withstand the blast load, while the structure with restrained walls is capable of receiving explosive loads.
