Abstract
This study presents a vibration-based health monitoring of short span bridges by an inspection vehicle. How to screen health condition of short span bridges in terms of the drive-by bridge inspection is described. Feasibility of the drive-by bridge inspection is investigated through a scaled laboratory moving vehicle experiment. The feasibility of using an instrumented vehicle to detect the natural frequency and changes in structural damping of a model bridge is observed. Observations also demonstrate possibility of diagnosis of bridges by comparing patterns of identified dynamic parameters of bridges through a periodical monitoring. It is confirmed that the method for damage identification under a moving vehicle identifies the damage location and severity well.
