Abstract. The rise in terrorist attacks targeting various locations worldwide has underscored the importance of evaluating structures exposed to blast effects. Despite progress in the field, understanding the response of concrete-framed buildings to extreme loading conditions remains crucial before implementing any protective strategies. The majority of structures impacted by blasts or impacts were not originally designed to withstand such forces, making them particularly susceptible. Consequently, the development of new standards and guidelines for effectively countering explosive threats is a continuous effort. In this research, ANSYS was utilized to develop an in-depth finite element model of a CFST (Concrete Filled Steel Tube) Column. A three-dimensional model of a reinforced concrete column was selected for the analysis. This paper details the structural model’s response to simulated blast loads and introduces two alternative designs that could inform future protection measures. The findings indicate that enhancing the design of the column significantly improves its resistance to blast impacts.
