Design of Aerodynamic Model for Unique Arch Bridge

The model test is an effective means to verify the mechanical performance of the bridge structure and to ensure the structural safety. The accuracy of design and manufacture is the key of model test.For a arch ridge with curved beam and skewed arch, the model test based on the similarity theory is analysized in detail including selecting materials, designing the size of section and calculating the geometrical parameters and so on, and the simulation reults between model and prototype are evaluated.Meanwhile some key technologies and valuable matters for design of aerodynamic model are presented,which provides an important reference value for model design of bridge structures.
