NUMERICAL SIMULATION OF WIND INTERFERENCE EFFECT FOR A STADIUM AND A GYMNASIUM

The wind load of the long-span roof of a stadium and a gymnasium in Quanzhou was calculated by CFX10.0 software and the SST k ω − turbulence model. The numerical simulation of wind pressure on the surface of the roof of the gymnasium was carried on. A comparison between the wind pressure from the test and the simulation was made and the result showed that the two match quite well. The results in this paper verify the feasibility of numerical simulation of large roofs in wind engineering. Then, the wind interference analysis between the stadium and gymnasium was carried on. The effect to wind load in different relative positions of the long-span roof complex and their interference mechanisms were explored. An overall evaluation of the construction planning for the stadium and the gymnasium has been delivered. The difference of the interference effect on closer and farther covering is distinguished.
