<![CDATA[The structural modification planning of the Nurul Huda Kanni Mosque Building in Pinrang Regency requires an integrated structural analysis to ensure safety and compliance with applicable design standards. This study aims to implement Building Information Modeling (BIM) using Tekla Structural Designer 2026, analyze structural responses, and evaluate the adequacy of reinforced concrete elements. The analysis comprises static analysis under gravity, wind, and equivalent static seismic loads, as well as dynamic analysis using Response Spectrum Analysis (RSA), referring to SNI 1727:2020, SNI 1726:2019, SNI 2847:2019, and SNI 2052:2024. The static analysis produced maximum second-order drifts of 3.1 mm in Dir1 and 3.7 mm in Dir2, a maximum wind-induced resultant deflection of 3.6 mm, a resultant drift of 1.7 mm, and a maximum long-term slab deflection of 22.5 mm. The RSA yielded maximum seismic storey drift ratios of 0.587 in Dir1 and 0.577 in Dir2, with a maximum check ratio of 0.365. Following redesign, no structural element was classified as Fail, and all capacity ratios remained below 1.00. The results demonstrate that BIM implementation through Tekla Structural Designer 2026 effectively integrates modeling, structural analysis, design, evaluation, and redesign, producing a structural configuration that satisfies strength, stability, and serviceability criteria under the adopted standards..Keywords: Building Information Modeling, Tekla Structural Designer 2026, static analysis, Response Spectrum Analysis, reinforced concrete]]>
