| Abstract: |
Two new cable-stayed bridges have pushed the world record for the span length of cable-stayed bridges to over 1000m. The design of these bridges, both located in typhoon prone regions, is strongly influenced by wind effects during their erection. Rigorous wind tunnel test programmes have been devised and executed to determine the aerodynamic behaviour of the structures in the most critical erection conditions. Testing was augmented by analytical and numerical analyses to verify the safety of the structures throughout construction and to ensure that no serviceability problems will affect the erection process. This paper outlines the structural and aerodynamic properties of the structures and discusses similarities as well as interesting differences. |
