Abstract

Full-scale dynamic testing of structures can provide valuable information on the service behavior and performance of structures. With the growing interest in the structural condition of railway bridges, dynamic testing can be used as a tool for assessing the integrity of bridges. From the measured dynamic response, induced by instructed passing trains, modal parameters (natural frequencies, mode shapes and modal damping values) and system parameters (stiffness, mass and damping matrices) are obtained. A field load testing and visual inspections for the assessment of the SCC bridge durability under an actual service environment were conducted. The results indicate that the SCC superstructure is structurally performing very well, and the capacity–rating evaluation for the SCC Bridge can use rating factor of the existing methods for the conventional materials such as the allowable stress and load–factor.
