Abstract (EN): The efficiency of different probabilistic methodologies for the safety assessment of short span railway bridges is compared in the current paper. The Monte Carlo and the Latin Hypercube simulation methods are combined with two different procedures to enhance the efficiency of the assessment: one based on the extreme value theory and another that uses an approximation procedure based on the estimates of the failure probabilities at moderate levels for the prediction of the far tail failure probabilities by extrapolation. A composite bridge with six simply supported spans of 12 m and ballasted track is selected as case study for the crossing of the TGV-double high-speed train. In order to test the efficiency of the methodologies the running safety of trains due to loss of contact between the wheel and the rail is analysed. © 2016 Taylor & Francis Group, London.
