室内における非構造部材の地震時挙動を再現するVRシステムの構築

Improperly secured nonstructural components, especially on the upper floors of high-rise buildings subjected under long-period ground motion, can prove dangerous to human life. The fallen items such as furniture, ceilings and lighting fixtures could become fatal obstacles that prevent efficient evacuation. To alleviate this problem, devices to prevent furniture from overturning were designed. However, a low proportion of installation of these devices shows that people have insufficient awareness of earthquake risks. In this study, a VR system was developed to reproduce the motion of furniture, ceilings and lighting fixtures under seismic excitation simulated by the ASI-Gauss code. The developed VR is more realistic than traditional numerical simulation model in order to enhance residents’ awareness of earthquake risks.
