Abstract EN
Compared with medium and small span bridges, very limited attention has been paid on the research of the impact coefficient of long-span railway bridges.
To estimate the impact effects of long-span railway bridges subjected to moving vehicles, a real long-span railway cable-stayed bridge is regarded as the research object in this study, and a coupled model of vehicle-bridge system is established.
The track irregularities are taken as the system excitation and the dynamic responses of the vehicle-bridge system are calculated.
The impact effects on main girder, stayed cable, bearings, and bridge tower are discussed at various vehicle speeds.
The results show that different components of the long-span railway cable-stayed bridge have different impact coefficients.
Even for each part, the impact coefficient is also different at different local positions.
It reveals that the impact coefficients in the actual situation may have significant differences with the related code clauses in the present design codes.
