TL;DR: In this article, a non-contact dynamic displacement measurement system for railway bridges based on video technology is presented, consisting of a high speed video camera, an optical lens, lighting lamps and a precision target, which can perform measurements with acquisition frame rates ranging from 64 fps to 500 fps.

TL;DR: In this paper, the calibration of the numerical model of a bowstring-arch railway bridge based on modal parameters was performed using a genetic algorithm that allowed obtaining the optimal values of fifteen parameters.

TL;DR: In this paper, an experimental calibration of a three-dimensional numerical model of an Alfa Pendular train vehicle based on modal parameters was performed using a submodeling/multistep approach involving two phases.

TL;DR: This paper aims to present a comprehensive literature review of the problematic associated with the train running safety assessment on bridges and gives a brief description of the available train-bridge interaction models needed to explicitly assess the traffic stability.

TL;DR: In this paper, the calibration of a numerical model of a masonry arch railway bridge using dynamic modal parameters estimated from an ambient vibration test is presented. But the calibration methodology relied on a genetic algorithm strategy which allowed estimating and updating numerical model parameters, particularly the elastic properties of materials.
