In the past few decades, the impact of explosions on buildings has been the area of research, mainly because buildings worldwide are increasingly facing the risk of deliberate explosion attacks, accidental explosions, and other forms of related explosion failure. The magnitude of the explosive load generated by most explosions is much higher than the design load of conventional structural engineering. As a result, with the intensification of global terrorist attacks, building owners, government departments, and design professionals have become more aware of the vulnerability and survivability of structures to explosive loads. Although much work on the impact of explosions on infrastructure continues, especially in India, numerical work to test explosives has been restricted. In addition, there are few computational tests for reinforced concrete beam-column joint to withstand explosive loads within a close range with a ruler spacing of less than as mentioned in IS: 1449. This may be due to the unreliable accuracy and relatively low survivability of most tools in this area.
