During the last 15 years the technique of computer modeling in wind engineering has been developed in the department of civil engineering at the University of Arkansas. Using these techniques, drag and lift coefficients for a bridge girder section were computed to start with and verified with wind-tunnel measurements. The model is further validated in this work. The influence of grid refinements will be studied in detail. Then the model will be modified to compute the critical flutter speed of a bridge cross section and verified by comparison with wind-tunnel measurements. This method would reduce the cost compared to wind-tunnel study by 10 times.
