Modal Identification of a Railway Bridge Under Train Crossings: A Comparative Study,. Specifically, it focuses on the variations in the dynamic behavior of the bridge observed under train crossings and those obtained from ambient vibrations. The bridge, whose dynamic response is under scrutiny, presents peculiarities in terms of its boundary conditions. They significantly differ fr
