Technology for the real-time monitoring of bridge safety is required by bridge management authorities and one task the National Center for Research on Earthquake Engineering (NCREE) has continually researched and developed. How to conduct real-time monitoring of long-range, multi-span bridges economically and effectively has remained the most significant challenge for the related research and development. In recent years, NCREE has significantly improved the manufacturing of fiber optic sensor instruments, fiber optic welding, and communication capabilities, allowing the center to conduct real-time monitoring of long-range, multi-span bridges.
