| 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. |
