Mitigation Measures Research of Vortex-Induced Vibration of the Forth Nanjing Yangzi River Bridge

Abstract:

The wind tunnel testing of large scale section model of the Forth Nanjing Yangzi River Bridge was conducted by the section model with a scale of 1:20. The details of the bridge girder could be simulated more precisely with a large scale. In the testing, a comparison was between the original girder cross section and the girder section without rails and tracks in the attack angle of +5°. On top of this, the main factor that causes the vortex-induced vibration of the girder was due to the installation of guide rail in the bottom of the girder. The control of vortex-induced vibration research was conducted concerning the installation of the guide rail.
