| Abstract: | The optimization of building-complex arrangement and the design of structural wind resistance require an exact prediction of wind environment around the building complex. In view of the importance of wind environment, a numerical simulation (CFD) is introduced for the prediction of wind effect around the building complex. The wind velocity and pressure in various building arrangements are simulated and analyzed. A reasonable pneumatic layout for given buildings is obtained. The wind tunnel test can be carried out based on the prediction of the numerical simulation. At the same time, the numerical simulation can provide a scientific basis for the optimization of the building-complex arrangement and the design of structural wind resistance. |
