This study evaluates the progressive collapse resistance of two reinforced concrete (RC) buildings, one with 3 stories and the other with 9 stories, both designed according to the Turkish Building Earthquake Code (TBEC-2018). The assessment focuses on the building's structural performance under extreme loading conditions, particularly in the context of potential progressive collapse.Nonlinear dynamic analyses were conducted using Extreme Loading for Structures (ELS) software, which employs the Applied Element Method (AEM) for detailed simulations of structural behavior. The study explores critical scenarios involving the removal of ground-floor columns at six different locations within the building plans. These scenarios were selected as they represent high-risk conditions for initiating progressive collapse. The results of the analyses were then compared with the criteria outlined in the Unified Facilities Criteria (UFC) guidelines, a widely recognized standard for assessing progressive collapse potential. The findings reveal that both the 3-story and 9-story buildings exhibit sufficient resistance to progressive collapse, regardless of height differences. The structural response in all scenarios showed minimal plastic deformations and no significant damage, indicating a high level of robustness in the designs. These results suggest that the provisions of TBEC-2018 are effective in reducing the risk of progressive collapse in RC structures, particularly in seismic regions. The study contributes to a better understanding of how current design codes influence building resilience and offers insights for future design and evaluation practices aimed at enhancing the safety of RC structures in earthquake-prone areas.
