| Abstract: | Flutter, buffeting and yortex-induced vibrati0n of Xiling Changjiang bridge were investigated in wind tunnel. The aeroelastic mod els of construction and application stage bridge were immerged in the smooth and turbulent flow respectively in the test. Flutter velocity and buffeting amplitude were presented. The results show that the flutter velocity is much higher than the design value of flow velocity and no vortex-induced vibration can be measured in the test. |
