This paper analyzes structural models of dual system building, and flat slab-drop panels strengthened with shear walls to present their seismic behavior. In this study, the main structure is focused on a multi-story building, and the Jogja Apartment is selected as a research object due to the use of a flat slab-drop panel system with shear walls. The capacity of column-plate joints to resist shear forces against structural damage is essential to simulate how the building’s performance and behavior are subjected to seismic actions. This study analyzed the Jogja Apartment structure using a flat-slab system drop panel with the shear wall (Model 1) compared to another structural model using a dual system (Model 2). The structure responses include base shear forces, story drift, and story displacement. The analysis refers to the previous codes, such as SNI 2847-2013, SNI 1726-2012, SNI 1727-2013, and PPIUG 1983, where the new regulations had not been updated yet when the building was officially designed. The structural analysis was carried out using ETABS v13 software. The analysis results show that the base shear force of Model 2 decreases in both X and Y directions compared to the primary shear force of Model 1. In contrast, Model 2 significantly produces lesser seismic behavior than Model 1, demonstrating their displacement and story drift. Based on the results, it can be concluded that the strength of the structural Model 1 in withstanding earthquake forces is more robust than Model 2.
