The Aerodynamic Behaviour of the Deck of Stonecutters Bridge, Hong Kong

Stonecutters Bridge is currently under construction in Hong Kong, with a main span of 1018 m. It will become one of the longest span cable-stayed bridges in the world on its completion at the end of 2009. The design of the bridge deck contains a number of interesting aerodynamic features including the streamlined steel twin box-girder deck structure and the associated guide vanes installed at the underside of the deck. A bridge of this span will be subject to a variety of wind-induced vibration problems, including vortex-induced response, buffeting response and flutter instability. This, coupled with the extreme typhoon wind climate in Hong Kong, necessitated extensive aerodynamic investigations to address the abovementioned aeroelastic problems. A summary is given of the investigations concerning the deck of the bridge.
