Abstract
Aerodynamic stability is one of the most important themes in the design of super long-span bridges. In order to improve aerodynamic stability, various researches were conducted and it was confirmed that slotted box girder with some devices shows good aerodynamic stability (J. Wind Eng. Ind. Aerodyn. 88 (2000) 297). In this paper, the results of full aeroelastic model test and flutter analysis (two- and three-dimensional) for a generic super long-span bridge, whose main span is 2.8 km, are described. It was confirmed that slotted box girder was applicable for the super long-span bridge for the reason that it is excellent in economical efficiency and aerodynamic stability.
