Technologies of analytical and experimental modal analysis have been investigated for their application in damage detection of bridges. In the context of experiments performed on a typical highway bridge in North Carolina, various signals and signal-processed data that can be used for interrogation are presented. By introducing simulated failures in a highway bridge in Pennsylvania and in a number of laboratory bridge models and analytical models, experimental results are examined for their ability to detect faults.read more
