摘要 采用计算流体力学软件Fluent得到凉都体育中心体育馆屋盖的风压力分布,进而得出体育馆屋盖的风压系数分布.对建筑间风遮挡效应进行了讨论,两体量相近的建筑物相邻时,下游建筑受到的风荷载往往更为不利.屋盖在风荷载作用下受向上的风吸力,屋盖不同位置的风压系数都不相同,且分布规律复杂,为简化设计计算过程,建议凉都体育馆屋盖体型系数可取为-0.9. The distribution of wind pressure on the gymnasium roof of Liangdu Sports Center is studied by applying the CFD software Fluent.Then wind pressure coefficient of the roof structure is obtained.Wind interference effect is also discussed.It shows that the building at backward position usually suffers more disadvantageous wind load than the upriver building when two similar scale buildings locate near each other.The roof suffers upward pressure under wind load.Wind-pressure coefficient varies a lot over the whole roof surface.It is advised that shape coefficient of this building can be-0.9,for simplifying the design computation.
