Abstract
The elevated railway station, above which a train is passing, is vulnerable to noise and vibration compared to other station types. To better identify the vibration characteristics of the elevated railway station, the transferred vibration from approach bridges should be analyzed. In this paper, through experiments and simulations, the transfer characteristics of the vibration from approach bridges is analyzed. The study structure is Geomgok station and the anaylses are conducted using ABAQUS three dimensional numerical model. To identify the change in the transfer characteristics for various bearing types, the analyses are performed considering mechanical properties of bearing for railway bridges. The measurement is performed using the accelerometers attached to the approach bridges and the station structure along the passing path of trains.
