Model structure health monitoring

Bridge vibration frequency is a measure of the overall state and structural damage will inevitably lead to changes in frequency. Based on this approach, we realized the bridge health monitoring system, introduced the bridge health monitoring system design approach, the data collection process and data analysis. Test proved that the vibration frequency of the bridge on the health status of the bridge. By the system design process and experimental results, from the experimental point of view, we can assess the overall state of the bridge model. Through this test, we can carry out health monitoring of bridge large-scale structures. It is important to bridge health monitoring. © 2010 IEEE.
