A damping formula is derived for determining the bridge damping ratio from the correlation of the front and rear wheels of a test vehicle using the modal components extracted by the wavelet transform (WT). Closed‐form solutions are derived for the dynamic responses of the damped bridge subjected to a moving two‐axle vehicle, from which the front and rear contact responses are calculated. The vehicle's body responses are the ones to be measured by the sensors fixed on the test vehicle during its passage over the bridge. The WT will be employed to extract the bridge damping ratio from the spatial correlation between the front and rear contact points of the two‐axle test vehicle. The chapter presents a brief overview of the vehicle–bridge interaction element subjected to a two‐axle moving vehicle. It assesses the reliability of the proposed procedure and formula for determining the bridge damping ratio.
