Abstract
Public buildings became most targeted by terrorist attacks using explosives. Due to terrorist attacks on public buildings, there is a tremendous loss of life, the economy, and extensive damage to the structures. This is primarily due to the intensity of the explosive and the type of explosive used. When a blast occurs, buildings around the point of explosion or nearer to it will be affected and damaged. The intensity and scale of damage to the facilities will depend on a few parameters like type of structure, height, shape, durability, and age of the building. Hence, these parameters will be vital in analysing structures subjected to blast loads. In this view, nonlinear dynamic analysis was performed on regular framed buildings with different aspect ratios to study the blast response. A blast load of intensity 2500 Kg TNT charge weight at a standoff distance of 10 meters was applied on all the buildings as mentioned above as a time history function using the software package SAP 2000 v20. Parameters like lateral displacement and acceleration of all the buildings are observed to know the blast response of the considered building with different aspect ratios. Based on the analysis, the less affected geometric size of the building is found for implementing the safe design of the structure to mitigate the loss.
