| 摘 要： | Taking a complex shaped high rise building as a case, the wind tunnel test with rigid model was carried out for wind load study. Meanwhile, with Fluent 6.1 software, the CFD numerical simulation had been performed with the RSM and the Non equilibrium Wall Functions. It was found that the results of the two methods were in good agreement. There were mainly positive pressures on the windward surface and negative pressures on the roof, the leeward surface and the side. Especially, negative pressure was higher in the leeward region at the building corner. And at the wind angle of 180°, the wind speed amplification effect was remarkable which was similar to those of canyons.
