| Abstract: | Using the theory of coupled vibration between bridge and vehicle, this paper makes an initial study on the lateral rigidity of piers of a medium small span simply supported girder bridge. By calculating and comparing the vibration responses of vehicle and bridge on the piers with different lateral stiffness, it points out that piers should have enough lateral rigidity to ensure the safety and stability for the running of high speed vehicles. |
