Abstract : This report presents the results of an aeroelastic investigation into the dynamic response of a cable-stayed bridge to wind loading. The investigation is a continuation of an earlier study in which the deck response was investigated for nine deck sections in three different flows. The present investigation used a plate girder section section only and was concerned with the effects of mass, yawed winds and erection phases on the response of the bridge to buffeting and a 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. Keywords: Flutter; Aeroelasticity; Buffeting; Wind tunnel tests; Wind tunnel models; Canada.
