Stonecutters Bridge, Hong Kong: design of steel deck

摘要

This paper describes the detailed design of the steel deck of Stonecutters Bridge in Hong Kong. The 1018 m main span deck and first 49 75 m of each back-span deck are steel, whereas the remaining lengths of back-span decks are prestressed concrete. The 53 3 m wide bridge deck consists of twin box girders connected by cross girders. The aerodynamic performance of the steel deck is fundamental to the overall behaviour of the bridge and the design is dominated by the dynamic effects of typhoon winds. Other design considerations including intense fatigue loading from heavy goods traffic and high summer temperatures were also influential in the design.
