For the bridge engineering, the bridge span gets longer and the style of bridge becomes more special. For these reasons, wind- induced instability of the bridges with high flexibilities becomes more important. To precisely predict the aerodynamic behavior of long-span bridges, the full model test was conducted in wind tunnel testing. The Rao-He-jie Bridge is an S-shaped bridge in the horizontal plane. The arch is linked to the bridge by several cables to increase the structural stiffness. This bridge with span of 157.943m is planned to be built in Taipei.

The full model with the geometric scale of 1/60 was constructed and tested at the Wind Tunnel of Tamkang University. In the wind tunnel tests, the dynamic responses of deck and arch were measured at different wind speeds. The experimental results show that the bridge has good stability under wind excitations. Flutter was not found as the wind speed achieves 80m/s. Buffeting response and the vortex shedding response were not significant at the design wind speed 56m/s.

碩士 === 淡江大學 === 土木工程學系 === 92 === The development of economics brings the advance of the technique of civil engineering. For the bridge engineering, the bridge span gets longer and the style of bridge becomes more special. For these reasons, wind- induced instability of the bridges with high flexibilities becomes more important. To precisely predict the aerodynamic behavior of long-span bridges, the full model test was conducted in wind tunnel testing.
The Rao-He-jie Bridge is an S-shaped bridge in the horizontal plane. The arch is linked to the bridge by several cables to increase the structural stiffness. This bridge with span of 157.943m is planned to be built in Taipei. Since its complexity of the structural system, the aerodynamic behavior of this bridge is needed to be investigated. The full model with the geometric scale of 1/60 was constructed and tested at the Wind Tunnel of Tamkang University. In the wind tunnel tests, the dynamic responses of deck and arch were measured at different wind speeds.
The experimental results show that the bridge has good stability under wind excitations. Flutter was not found as the wind speed achieves 80m/s. Buffeting response and the vortex shedding response were not significant at the design wind speed 56m/s.
