Abstract (EN): This study presents a dynamic evaluation of the Suaçui railway bridge considering the vehicle structure interaction and subjected to heavy axle load trains (HAL). For this purpose, three-dimensional finite element models of the truss bridge, including the track, and train were developed. The dynamic response was obtained using ABAQUS® software which was programed with an iterative uncoupled method for vehicle structure interaction considering track irregularities. The validation of the numerical models was performed through a comparison between numerical and experimental dynamic responses, in terms of displacements and acceleration of the bridge for the passage of DASH 9W Locomotives and GDE wagons. The experimental response obtained from a dynamic test under railway traffic revealed a good agreement with the numerical response. © 2016 Taylor & Francis Group, London.
