Abstract

Blast loading represents one of the most hazardous and destructive forces that structures may encounter throughout their life span. Understanding and mitigating the effects of such loading is crucial for ensuring the safety and resilience of buildings. This study focuses on analyzing the behavior of reinforced concrete (RC) frame structures when subjected to blast loading, with the aim of informing more robust and resilient building designs. The research specifically examines the deformation patterns of RC structures at varying standoff distances—namely, 3 m, 5 m, and 10 m—with an explosive weight equivalent to 113 kg of TNT. The study further investigates story displacement and drift across three types of building configurations: bare frame buildings, steel-braced buildings, and shear wall buildings. The findings reveal that the effects of explosive events diminish as the standoff distance increases, indicating the critical importance of distance in blast-resistant design. Moreover, the results show that story displacement is significantly lower in shear wall buildings compared to steel-braced buildings and bare frame structures, underscoring the superior performance of shear walls in mitigating blast-induced deformations. To ensure the reliability of the findings, the analytical results were validated through statistical analysis, which confirmed that all results follow a normal distribution. This comprehensive analysis not only provides valuable insights into the structural response under blast loading but also highlights the importance of considering different building configurations and standoff distances in the design process to enhance structural resilience against such extreme loading conditions.
