Building development in Indonesia, including in Banyuwangi Regency, requires structural planning that ensures earthquake resistance. The equivalent static analysis method is widely used due to its simplicity, particularly for low-rise buildings. However, regulatory changes from PPTIUG 1981 to SNI 1726:2012 have reclassified some structures—previously considered regular—into irregular categories. This shift necessitates a reassessment of the accuracy of using the equivalent static method. This study aims to evaluate the accuracy of the D-Value method on the 3-story hospital building of Al-Huda, focusing on three key parameters: inter-story drift, natural period, and structural stability (P-Δ effect). Calculations were conducted based on existing project data, structural analysis methods, and the requirements outlined in SNI 1726:2012. The analysis results indicate that the structure satisfies the criteria for a Type D structure. The values of inter-story drift, period, and stability remain within acceptable limits according to seismic design standards. Therefore, the use of the D-Value method within the framework of equivalent static analysis is still considered appropriate for this building.
