Abstract
Explosive loads have garnered a lot of attention lately because of numerous unintentional and deliberate occurrences that have affected important structures all over the world. As a result, there has been a lot of research in this area over the last ten years. Although the majority of the early studies were empirical, more recent studies have progressed into thorough and organised studies that focus on understanding the behaviour of structures subjected to blast loading conditions. These studies aim to evaluate the structural response, damage mechanisms, and possible mitigation techniques that can reduce the severity of blast effects on buildings and critical infrastructure. Researchers have increasingly used advanced analytical methods, numerical simulations, and experimental investigations to better understand the dynamic response of structural systems under explosive loading. Finite element modelling and computational techniques are now widely adopted to predict pressure distribution, structural deformation, and potential failure modes. In addition, several protective design strategies such as strengthening of structural members, use of energy absorbing materials, and blast-resistant structural configurations have been explored. These approaches help in improving the resilience of structures against sudden high-intensity loads.Furthermore, modern research emphasizes the importance of integrating blast-resistant design principles into building codes and engineering practices. The development of improved materials and innovative structural systems has also contributed to enhancing the safety and reliability of structures exposed to explosive threats. Overall, continued research in this field is essential for protecting critical infrastructure and ensuring the safety of occupants in vulnerable environments.
