Abstract
A long-span one-tower cable-stayed bridge is planned in the section between Port Island and Wada Cape (Kobe-Nishi sea route) on the Osaka Wangan Expressway Western Extension. This bridge is one of the world's longest one-tower cable-stayed bridges. The resistance to the vortex-induced oscillation becomes the problem due to the low frequency of the main girders of a long-span cable-stayed bridge. Therefore, wind tunnel test with spring supported sectional model of the box girder with different fairing shapes was conducted. As a result, a trapezoidal fairing shape with better aerodynamic resistance was found. In this paper, the outline of wind tunnel tests are described.
