Abstract

Buildings on soft soil are prone to large lateral deformation, so drift control needs to be considered together with its structural and economic consequences. This study examines a 13-story reinforced-concrete building through three ETABS models: an SMRF with shear walls, an OMRF open frame, and an OMRF fitted with fluid viscous dampers (FVDs). Response-spectrum analysis followed SNI 1726:2019. The selected scheme used 14 linear FVDs, reducing maximum deformation from 442.02 mm to 315.62 mm and bringing the maximum interstory drift back within the adopted limit. Quantity take-offs showed reductions of 8.83%, 24.10%, 19.30%, and 42.08% in slab, beam, column, and pilecap reinforcement, while the number of piles fell by 45.09%. All connection demand-to-capacity ratios remained below 1.0, although tensile concrete breakout was critical at 0.97. Material cost rose from IDR 8.49 billion to IDR 38.44 billion because FVD procurement dominated the alternative.
