Abstract
A multi-span cable-stayed bridge is planned for the Osaka Wangan Expressway Western Extension. The main girders of a multi-spam cable-stayed bridge have a low deflection frequency. And it makes wind resistance to vortex-induced vibration a problem. In addition, the separated two-box girder cross section make wind resistance to vortex-induced vibration a problem. Therefore, spring support tests using a partial model with different fairing shapes of the box girders and wind-resisting additives were conducted on the separated two-box girder cross section of this bridge to investigate a main girder cross-sectional shape with high wind stability.
