| Abstract: |
Based on the structural health monitoring system of Shenzhen Bay Bridge, the wind parameters and cable vibration properties are acquired by analyzing the test data during the two typhoons period in 2007. The result shows that the horizontal fluctuating wind power spectrum is consistent with the SIMIU spectrum and the vertical fluctuating wind power spectrum is basically consistent with the PANOFSKY spectrum. Moreover, the side span cables appeared a significant rain-wind induced vibration, while the vibration amplitude of long cables in the main span has been effectively controlled because of the installation of cable dampers. The short cable in bridges similar to Shenzhen Bay Bridge should be considered to take additional damping device or auxiliary cables. |
