| Abstract: | The article numerically simulates the two-dimensional flow field of the double-floor deck steel-truss girder by using the current finite element program ANSYS, gives the surface pressure and speed distributions of the double-floor deck steel-truss girder in the flow field. The integration of surface pressure can achieve the static wind three-component coefficient. The article validates the feasibility to realize the wind tunnel numerical simulation of the sectional two-dimensional flow field of bridge by CFD method. |
