Effect of Mass, Wind Angle and Erection Technique on the Aeroelastic Behaviour of a Cable-Stayed Bridge Model

摘要

Results are presented of an aeroelastic investigation into the dynamic response of a cable-stayed bridge to wind loading. This is a continuation of an earlier study in which the deck response was investigated for nine deck sections in three different flows. The present effort used a plate girder section only and was concerned with the effects of mass, yawed winds and erection phases on the response of the bridge to buffeting and torsional instability. The model, built at a geometric scale of 1:75, was tested in the NAE 9 m X 9 m low-speed wind tunnel.
