摘要
本文主要给出了湖南益阳体育场大悬挑屋盖平均风压分布的数值模拟结果,并将0°风向角下的结果与风洞实验进行了比较,两者大体上是吻合的.随后简要给出了体育场内和屋盖附近风流场的规律性.本文的数值模拟结果说明了数值模拟在大悬挑屋盖风工程中应用的可行性,特别是在初步设计中的优越性与现实性.
The numerical simulation study of mean wind pressures on the large cantilevered roof of Yiyang Stadium, Hunan province was carried out in this paper. The comparision of the distribution of wind pressures on the roof with the results of wind tunnel test in the 0° direction shows that they are consist with each other. Some rules of wind flow fields in the stadium and around the roof were also discussed briefly. The results in this paper verify the feasibility of numerical simulation of large cantilevered roofs in wind engineering, especially in the preliminary design.
