[Case Study] Demonstration Experiment of Earthquake Monitoring for Nagoya Bridge

It was trial-introduced for the understanding of complex behavior during large-scale earthquakes and the refinement of response analysis techniques.

This is an introduction to a case where 'sonas x01' was adopted for a demonstration experiment aimed at clarifying the damage mechanisms of infrastructure structures, such as bridges, by measuring their vibrations during earthquakes and translating that knowledge into reinforcement and design methods. In constructing this monitoring system, there were no locations available for a fixed power supply, so it was required that all nodes, including the master unit and nodes for internet connection, be battery-operated, and that they have a data upload function to confirm acceleration data during an earthquake without needing to go on-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 clarify the damage mechanisms of structures. ■ Reason for Selection - The power-saving capability that enables continuous monitoring outdoors without a power supply was a key point. *For more details, please refer to the PDF document or feel free to contact us.
