摘要

Health monitoring has been one of particular concerns of the engineering community in Japan. Effective monitoring, reliable data analysis, rational data interpretation and correct decision making are challenging problems for engineers who specialized in bridge monitoring field. In this paper, the status of health monitoring of long-span bridges in Japan is briefly reviewed. The monitoring system was developed to be a reliable device to observe the bridge in earthquake and/or typhoon accurately, besides have a self-check function to sense the disorder of the system itself. Current practices in health monitoring of bridges are represented by the example of Akashi Kaikyo Bridge monitoring system. The reliability of the current monitoring system is confirmed by comparing the analyzed simulation results and field-measured results. Furthermore, a newly developed monitoring system is proposed to provide information for structural health maintenance, so called Monitoring Based Maintenance (MBM). This monitoring system is easily accessible, economically feasible and durable through efforts in development of innovative sensors and new generation of automated remote monitoring technology.
