Wind tunnel tests were conducted on a model of deck section from the Ting Kau cablernstayed bridge. The purpose of the tests was to determine the set of aerodynamic derivatives conventionallyrnused to describe the motion-induced forces arising from the wind flow, and to investigate the stability ofrnthe deck under different conditions of turbulence and angle of attack. The study shows that except forrnlarge negative angles of attack the deck section itself is stable up to a high wind speed, and that whenrninstability does occur it is essentially a single degree of freedom (torsional) flutter.
