Fatigue Life Assessment of Intercity Track Viaduct Based on Vehicle–Bridge Coupled System
نویسندگان
چکیده
During the long-term operation of an urban railway viaduct, it is subjected to multiple cyclic loads caused by movement a vehicle. As result, fatigue life bridge should be fully considered during design process. Furthermore, structure will subject environmental corrosion for extended period time, resulting in concrete carbonization and reinforcement corrosion, which aggravates structure’s damage. To compensate disadvantage traditional static analysis method’s inability consider vehicle speed, vehicle–bridge system coupled model established, material considered, damage under load analyzed, service common 30 m 25 span bridges calculated. The results show that ignoring understate damage, speed has significant impact on life. Finally, recommended operating speeds are provided.

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
