In this paper,the wind effect of a large-span gymnasium in Tianchang City was simulated by numerical wind tunnel using the turbulence model of large eddy simulation(LES),and the distribution law of the average wind pressure and fluctuating wind pressure and the wind load duration of the gym-nasium were obtained.The wind vibration coefficient and equivalent static wind load of the gymnasi-um roof were calculated by the gust load factor method.The results were compared with those of wind tunnel test.The results show that the wind pressure distribution on the surface of the gymnasi-um evaluated by numerical simulation is in good agreement with the wind tunnel test results,proving that LES can better reflect the wind pressure distribution on the surface of the large-span gymnasium.The wind vibration coefficient and equivalent static wind load calculated by the two methods are basi-cally the same,indicating that the wind load of large-span spatial structure can be effectively predicted by LES technology.The research results can provide technical reference for the wind resistance design of large-span gymnasium.
