Abstract:
This paper used CFD to calculate the physical parameters correlated to wind load on bridge, discussed the variation of three component coefficients with Reynolds number based on two typical bridge sections with FLUENT software for numerical simulation, established actual scale models, by selecting reasonable type of meshing form. Three different turbulence models were used in the analysis, the numerical calculation results were compared with the one of wind tunnel test. The results show that CFD can be used to calculate bridge sections with actual size so as to avoid the insufficient of scale model in wind tunnel test. The calculation has the characteristic of low cost, high speed and complete materials, which can provide a platform to simulate the real and ideal condition. 7 tabs, 6 figs, 15 refs.
