Quantification of Indoor Damage Using an Indoor Seismic Motion Evaluation System
Year: 2025
Type: conference-paper
Abstract: In the performance design of buildings during earthquakes, it is required not only to ensure structural safety, but also to reduce indoor damage such as damage to nonstructural members and toppling of furniture and fixtures, and and to aim to maintain functionality and provide a safe and secure building even after an earthquake. Then, we developed TAFT®, a tool that simulates and visualizes the shaking of an interior during an earthquake using a physics engine, and released some of its functions as a web application to the public in 2014. The system can instantly reproduce the shaking of a room at the time of an earthquake in CG animation according to the conditions of the building and earthquake motion set by the user. Furthermore, by applying the physics engine of the Unity game engine to TAFT®, it is now possible to import CAD data for larger rooms and furniture, and to move within a room, and by outputting high-quality VR images to screens and HMDs, it is possible to experience earthquakes with a high sense of realism. A high-resolution VR version of TAFT® is also available as a web application that can be run on ordinary office notebook PCs. This enables visualization of the application effects of seismic isolation and vibration control technologies at meetings with building owners, and is used as a communication tool with building owners in the early stages of design. Furthermore, we attempted to show both qualitatively and quantitatively the situation of room shaking during an earthquake by quantifying the degree of room danger during an earthquake based on the data of each furniture movement obtained from this simulation system.
