Title: Evaluation of dynamic effects and fatigue assessment of a metallic railway bridge
Issue Date: 2010
Abstract: In the framework of the national research project 'Evaluation of the structural integrity of metallic railway bridges', the Laboratory of Vibrations and Monitoring of the Faculty of Engineering of the University of Porto, Portugal has recently developed a study concerning the assessment of the dynamic behaviour and fatigue condition of a metallic railway bridge on the international 'Beira Alta' route in Portugal. This paper describes the numerical simulation of the dynamic behaviour of the bridge under railway traffic, the experimental updating and validation of the finite-element model used, and the estimation of the fatigue residual life using different code specifications and the characteristics of real trains crossing over the bridge.
