    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.
