[Case Study] Demonstration Experiment of Earthquake Monitoring Targeting the Nagoya Bridge

It was trial-introduced to understand the complex behavior during large-scale earthquakes and to refine response analysis techniques.

This is an introduction to a case where 'sonas x01' was adopted for a demonstration experiment aimed at elucidating the damage mechanisms of infrastructure structures, such as bridges, by measuring their vibrations during an earthquake, and translating that into reinforcement and design methods. In constructing this monitoring system, there was not a single location where a fixed power source could be utilized. Therefore, it was required that all nodes, including the master unit and nodes for internet connectivity, be battery-operated, and that they have a data upload function to confirm acceleration data during an earthquake without having to go to the site. Such requirements, which are considered difficult with general sensor network technology, were achieved with this product without the need for additional special implementations or settings. 【Case Study】 ■ Installation Site: Yokohama National University ■ Challenges Before Installation - Earthquake monitoring was necessary to elucidate the damage mechanisms of structures. ■ Reason for Selection - The power-saving capability that enables continuous monitoring outdoors without a power source was a key factor. *For more details, please refer to the PDF document or feel free to contact us.
