New proposal for the shaking issue! Simple evaluation with an iPhone app.
- Background of Development The vibrations felt within a building can significantly impair the comfort of its residents. Until now, our company has conducted surveys using high-sensitivity seismometers, referencing the "Evaluation Standards for Residential Performance Regarding Building Vibrations" by the Architectural Institute of Japan (2018). However, while we were able to grasp the details of the vibration situation, the cost burden for customers was substantial, often leading to hesitation in conducting surveys. Our company felt the need to provide a more accessible and straightforward method to address the issue of "vibration" that buildings face. - Overview and Features of the App Against this backdrop, our company has developed an iOS app that allows for easier evaluation of building vibrations. This app is installed only on iPhone devices owned by sales and technical personnel, and measurements are conducted on-site by sales representatives based on inquiries from customers.
