Abstract

The arrangement of shear walls plays a fundamental role in controlling the seismic behavior of reinforced concrete buildings by affecting lateral stiffness and structural deformation during earthquake loading. This study investigates the seismic performance of the Ristia Resort reinforced concrete building subjected to three alternative shear wall layouts. Three numerical structural models with identical geometry, material properties, loading conditions, and seismic design parameters were developed, with the shear wall locations defined as the only variable. Seismic performance was evaluated through response spectrum analysis based on SNI 1726:2019. The evaluation considered inter-story drift, story stiffness, and the proportion of design base shear carried by the shear wall system. Among the investigated configurations, Model 1 achieved the best structural performance by reducing the third-floor inter-story drift by 10.69% and 11.19% relative to Models 2 and 3, respectively. It also increased the average X-direction story stiffness by 6.38% and 6.48%, while the shear wall system resisted 66.74% and 71.08% of the design base shear in the X- and Y-directions, respectively. These results demonstrate that a symmetrical shear wall arrangement provides a more efficient lateral load-resisting system and improves the overall seismic performance of reinforced concrete buildings.

Abstract

Hospitals are classified as essential facilities and therefore require adequate seismic performance to maintain structural safety during earthquake events. This study compares the seismic performance of a conventional slab system and a flat slab-drop panel (FSDP) system in a four-story reinforced concrete hospital building using the Response Spectrum Analysis (RSA) method. Two three-dimensional structural models were developed in ETABS v21.2 with identical geometry, material properties, loading conditions, and boundary conditions. The only variable considered was the floor system configuration. Structural responses, including structural weight, fundamental period, inter-story drift, slab deflection, base shear, and column reinforcement demand, were evaluated in accordance with SNI 1726:2019 and SNI 2847:2019. The results indicate that the FSDP system increased the total structural weight by 6.54%, the fundamental period by 30.2% and 18.2% in the X- and Y-directions, respectively, and the base shear by 42.29% and 26.85%. In addition, the FSDP system produced larger inter-story drift, slab deflection, and column design demand than the conventional slab system. Nevertheless, all evaluated structural responses satisfied the design requirements specified in the applicable Indonesian standards. Overall, the conventional slab system was found to be more structurally efficient, exhibiting lower inter-story drift, slab deflection, base shear, and column reinforcement demand than the FSDP system, while both structural systems satisfied the seismic design requirements specified in SNI 1726:2019 and SNI 2847:2019. The FSDP system, however, offers greater architectural flexibility and construction efficiency.
