Abstract This study aims to evaluate the structural performance of a reinforced concrete building through ‎numerical modeling using ETABS. The analysis focuses on the distribution of internal forces and the ‎capacity ratio of structural elements under ultimate load combinations based on the LRFD method. The ‎case study is the upper structure of the BBPSDMP Kominfo Office Building in Makassar. The results ‎indicate that the maximum axial force occurs in the first-floor column, reflecting the accumulation of ‎vertical loads from the upper levels. The evaluation of structural capacity shows that the maximum ‎capacity ratio reaches 0.977, which is still below the allowable limit of 1.0, indicating that all structural ‎elements satisfy the design requirements. However, elements with ratios approaching unity, particularly ‎columns at the lower levels, are identified as critical components that govern the structural performance. ‎This study demonstrates that numerical analysis using ETABS is effective in identifying both the ‎distribution of internal forces and critical structural elements. The findings provide practical insights for ‎structural evaluation and design optimization of reinforced concrete buildings to ensure safety and ‎reliability.‎
