| Skew bridges induce inherently coupled bending and torsion response. The actual relevance of this coupling in the dynamic response of this relatively common type of deck (slab supported on multiple I-beams for double-track width) is not well known. This paper presents the study of the dynamic behaviour of a skew I-beam railway bridge of the Valencia-Tarragona line in Spain. Both experimental and numerical analysis have been carried out. The experimental study consists of an Operational Modal Analysis (OMA) of the bridge from the data provided from 20 high-sensitivity accelerometers attached underneath the deck. The monitoring system is completed by six strain gauges attached to rails in groups of two. For the numerical study, different models have been used, including 2D analysis with the software Caldintav and 3D FEM analysis with Abaqus. | |
