Dynamic behavior of high speed railway bridges in interoperablelines

摘要

In this work, dynamic analyses of different structural types of bridges under highrnspeed railway loading were carried out, towards the assessment of its dynamic behavior inrninteroperable lines, in which the Technical Specifications for Interoperability (TSI) arernapplicable. The analyses were made for the passage of real trains and the loading schemesrnrelative to the High Speed Load Model. The responses were evaluated from the point of view ofrnstructural safety, track safety and passengers comfort, based on the criteria established in thernEN1991-2 and EN1990-AnnexA2.
