Indonesia is a country located within a high seismic hazard zone, making the design of earthquake-resistant building structures a critical aspect, particularly for essential public facilities such as hospitals. Hermina Mekarsari Hospital was previously designed for a region with moderate seismic risk and employed only a Special Moment Resisting Frame System. This study presents a redesign of the building structure for application in a high seismic risk area through the implementation of a dual system, which combines Special Moment Resisting Frame System and shear walls to enhance structural stiffness and the capacity to resist lateral forces. The structural analysis was performed using the ETABS software in accordance with SNI 1726:2019, SNI 2847:2019, and SNI 1727:2020. The results indicate that the frame system is capable of resisting 25.08% of seismic forces in the X direction and 26.19% in the Y direction, while the shear walls resist 74.92% in the X direction and 73.81% in the Y direction. These values satisfy the minimum requirement for frame seismic force resistance of 25% as stipulated in SNI 1726:2019. Furthermore, the inter-story drift, mass participation, and base shear checks are found to comply with the limits prescribed by the standards.
