TL;DR: In this paper, the response of the contact point of the vehicle with the bridge, rather than the vehicle itself, was proposed for modal identification of bridges by a moving test vehicle, and approximate closed-form solutions were derived for the vehicle and contact-point responses, and they were verified by finite element solutions.

TL;DR: In this article, the authors used the contact point response of a moving test vehicle for the damage detection of bridges, where the Hilbert transform was used to calculate the instantaneous amplitude squared (IAS) of the driving component of the contact-point response.

TL;DR: The vehicle scanning method (VSM), an indirect approach for bridge measurement, has attracted intensive attention since it was proposed and is currently being applied to bridge measurement in China.

TL;DR: In this article, a simple theoretical framework is presented for identifying the damping ratios of simply supported beams using a two-axle moving test vehicle, equipped with uniformly spaced accelerometers and laser sensors.

TL;DR: In this paper, a comparative study is conducted for the responses of soil-tunnel systems to moving train loads using the 2D and 2.5D finite/infinite element approaches, considering the effects of train speed, rail roughness and floating slab.
