- W2392132031 abstract "In order to find the main girder section with better aerodynamic characteristics for super-long-span bridges and to advance the construction development of super long-span bridges in China,five kinds of main girder section were proposed in the prototype design of super long-span bridges.The aerostatic and aerodynamic parameters of the main girder sections were obtained by the CFD numerical simulation method.The critical wind speeds of aerostatic instability and flutter were further calculated for the five kinds of main girder section respectively.The performance of aerostatic stability and flutter stability of these girder sections were compared.It is shown that(1) two-box girder and three-box girder have better aerodynamic characteristics;(2) the aerodynamic characteristics of single-box girder and two-box girder have been greatly optimized,and there is great room for optimization of three-box girder,while the aerodynamic characteristics of oval girder and gravity girder are poor,and there is little value for their optimization." @default.
