Abstract

The structural design of modern hospital buildings must ensure both functional performance and high seismic resilience, particularly in earthquake-prone regions such as Jakarta. This final project analyzes the modification of the Dharmais Woman and Child Cancer Care Hospital by replacing the original reinforced-concrete (RC) shear wall system with a Steel Plate Shear Wall (SPSW) system combined with composite steel–concrete members. The study includes modelling and analysis in ETABS in accordance with SNI 1726:2019, SNI 1727:2020, and SNI 1729:2020, covering gravity and seismic load combinations, SPSW design, composite beams and columns, foundation design, and connection detailing. A comparative evaluation is then made between the modified SPSW structure and the existing RC shear-wall building in terms of dynamic characteristics and seismic performance.Response-spectrum analysis shows that the SPSW system slightly increases the lateral stiffness of the building. The fundamental periods in the X- and Y-directions decrease from approximately 3.265 s and 3.482 s (existing RC structure) to 3.179 s and 3.310 s (SPSW composite structure), corresponding to a stiffness increase of about 3–5%. Dynamic base-shear demands in the modified structure are on the order of 1.28×10⁴ kN (X) and 1.22×10⁴ kN (Y), which are about 11% and 6% lower, respectively, than those of the existing RC shear-wall system due to differences in stiffness distribution and effective seismic mass. Inter-story drift checks confirm that both configurations satisfy the SNI 1726:2019 drift limit of 2% of story height; however, the SPSW system reduces the maximum drift from about 47 mm to 32 mm in the X-direction (≈32% reduction) and from about 52 mm to 49 mm in the Y-direction (≈7% reduction). These results indicate that the SPSW–composite system can provide comparable or improved seismic performance relative to the existing RC shear-wall structure while maintaining acceptable drift control and ductile structural behavior, making it a viable alternative for high-rise hospital structures in high-seismic regions.
