Numerical Simulation of Mean Wind Pressure on the roof of Yantai Gymnasium
In order to determine the distribution of wind load on the roof, wind tunnel test and numerical simulation are both carried out.Then the distribution of mean wind pressure under different wind directions is obtained and the features of mean wind pressure are also analyzed.The datas show that wind pressure distribution of the roof is predominantly negative pressure; only a small area of windward side is positive pressure distribution.The peak of negative pressure appears at the roof ridge or windward long eaves, and varies as changes of wind direction.Meanwhile, the comparison between the results of the numerical simulation and wind tunnel test shows that the distribution law of both is almost the same, but in some areas that flow separation is serious, the error is larger.Then the reasons for the error are discussed.
