| Research Abstract |
The foundation of the remote monitoring system using the telephone circuit was developed as the monitoring of bridge structure. Intelligent monitoring system which applied FOS( Fiber Optic Sensor ) is also developed to measure internal damage distribution of RC member and fatigue crack extension.
Bridge integrity is evaluated diagnostics including these data, and an optimum bridge management system was developed. This diagnostic evaluation of bridge integrity was improved the judgment of diagnostic evaluation with the application of Fuzzy Quantification Theory of Second Kind, and bridge integrity evaluation including seismic performance are also analyzed in this research.
