Abstract
This Paper describes the fundamental aerodynamic characteristics of two edge girders, which would be used for the bridge girders of future long span cable stayed. For the purpose of the aerodynamic stabilization of two edge girders, we considered the girder, which was inclined low flanges for controlling the flow field around lower side of two edge girder sections, because the vertical and horizontal plates on lower side was effective for aerodynamic instability through various wind tunnel tests. Therefore, the aerodynamic effect of two-edge girders with inclined lower flange was investigated by unsteady aerodynamic characteristic based on measurement of aerodynamic forces.
