Nonstructural components such as furniture, ceilings, and lighting equipment exhibit varying behaviors during earthquakes influenced by factors such as seismic waves, floor heights, friction coefficients of floors, and the proximity of other objects. These variables can differ in each scenario, rendering it challenging for individuals to understand and implement effective seismic protection measures for these components. Under these circumstances, this study aims to develop an integrated finite element analysis and virtual reality (VR) system to simulate and visualize the behavior of indoor nonstructural components under seismic excitation. The finite element analysis system was developed using an adaptively shifted integration (ASI)–Gauss code, and the VR system was implemented using Unity software. For the analysis, the models of the furniture and ceilings were placed on the 1st, 5th, and 10th floors of a 10-story reinforced concrete building model. The seismic response was analyzed using the 100% 1995 JMA-Kobe seismic wave as the input. The results indicated that the 10th floor experienced the most severe damage, with complete ceiling collapse and furniture overturning. On the 5th floor, the ceiling underwent significant plastic deformation without collapsing, and the furniture moved and swayed but remained upright. On the 1st floor, the furniture also moved and swayed, with one piece toppling over. These findings highlight the variability in damage across different floors. Finally, this damage was realistically visualized using VR goggles, which could serve as a powerful tool to enhance public awareness of disaster prevention and mitigation.
