| Abstract: |
This work presents a fatigue assessment method, applicable in normal and in resonance conditions, based on the dynamic analysis of the bridge and on the linear damage accumulation method. The determined damage levels include the single train passages and the train crossings, the later determined by a new method based on a random simulation of the crossing point. |
