| Outline of Final Research Achievements |
Maintenance of aging infrastructures is a growing problem. Cost-efficient maintenance and management of civil infrastructures require balanced consideration of both structural performance and the total cost accrued over the entire life-cycle considering uncertainties. For that purpose, inspection and monitoring techniques for aging existing structures have been proposed.
Mechanoluminescent (ML) can be a useful tool to inspect existing infrastructures.
In this study, the system for measuring ML intensity was newly developed and was applied to unconfined compression test. Measured ML intensity was compared to the applied stress. The relationship between ML intensity and applied stress shows unique curve, and the applied stress can be visually estimated based on ML.
