The model represents an existing multi-story full-scale steel structure located in the United States once, incorporating realistic geometric and structural characteristics. The structural system comprises rigid beam-to-column connections, ensuring full moment transfer across joints. The frame geometry includes seven spans in the longitudinal direction and three spans in the transverse direction, with non-uniform bay widths and varying story heights, reflecting a realistic high-rise configuration. Three critical column removal scenarios were modeled: (1) the middle of the short side, (2) the middle of the long side, and (3) a corner column at the first story. AEM was adopted to simulate highly nonlinear phenomena. Removing the middle column on the long side resulted in the highest displacements, underscoring the critical influence of column location on progressive collapse vulnerability and robustness.}, number={2}, publisher={Çukurova Üniversitesi}
