Concrete Cracks Monitoring of a Practical Bridge by Using Structural Health Monitoring Technique

Concrete cracks monitoring of a practical bridge was discussed in order to investigate the practical application of structural health monitoring (SHM) technique. Some detail information of the SHM system of a practical bridge were introduced and some key issues for building this monitoring system was discussed. Strain of bridge beam generated near the concrete cracks was applied to assess the change of width of cracks, and the monitoring data were analyzed. The condition of this practical was evaluated from the point of view of the change trend of concrete cracks.
