| Abstract: |
An overall study of runability, comfort and safety aspects for real trains passing the planned Segundo Cruce del Lago de Maracaibo - Puente Nigale Bridge part of a fixed link across Lake Maracaibo in Venezuela has been carried out. For the analysis the AREMA codes apply. However, several Eurocodes defining design criteria for train/bridge dynamic interaction, train runability and cross wind effects has also been used. This paper shows how train runability has been checked through global analyses by use of a 3D FE in-house developed Integrated Bridge Design and Analysis System (IBDAS) [1] allowing for direct dynamic train/bridge interaction analysis, i.e. the dynamic trains modelled as minimum 14 DOF per coach are interacting directly with the global FE-model utilizing a modal approach. The dynamic modelling of five real trains has proved to be a highly valuable tool for examining the feasibility and safety of operating railway traffic on the fixed link. |
