Numerical Analysis on Variation of Dynamic Response of Girder Bridges with Torsional Reinforcement Panels

MATEC Web of Conferences, 2015
The dynamic flexural behaviour of the railway bridge is influenced by its torsional behaviour. Especially, in the case of girder railway bridges, the dynamic response tends to amplify when the natural frequency in flexure (1st vibration mode) is close to
