STATIC AND DYNAMIC PERFORMANCE EVALUATION OF BRIDGES THROUGH FIELD TEST AND MONITORING
This paper presents experimental load tests performed on a slab-on-girder prestressed concrete bridge. The bridge was tested under static, crawling loading, and dynamic loading. A full three dimensional finite element prediction under both static and dynamic loadings was carried out and the results were compared with the field measurements. Acoustic emission monitoring of bridge structures is not a new vista. Yet, even today the method has not been fully exploited in bridge monitoring as most evaluations are only qualitative and other NDT methods like ultrasonic have to be used to quantify the results observed from global monitoring. Though numerous quantitative methods have been proposed, they have not yet developed to be useful for actual field test of bridges. Therefore, an attempt was made to use the intensity analysis technique for damage quantificationusing acoustic emission method.
