中文摘要：
根据大型体育场常见的挑篷形式，设计具有一般性的悬臂弧形挑篷模型．在CFX5．5软件平台模拟的数值风洞中，研究弧形挑篷在不同风向角及不同挑篷倾角下的风压分布．结合大气边界层风洞中该模型的刚性测压试验结果，验证数值模拟计算的可信性．在系统分析了弧形挑篷表面风荷载分布的特点后，获得弧形挑篷表面风压分布的一般性规律．
英文摘要：
Wind pressure distributions on arc roofs of stadiums are numerically studied in this paper. A typical cantilevered arc roof model is first established. The variations of wind pressure distribution on the cantilevered arc roof with wind azimuth and roof obliquity are then computed on CFX 5.5 software platform. The results from a wind tunnel test of an arch roof model which has a similar configuration to that for the computation are adopted and compared with those from the present numerical simulation. The comparison verifies the reliability of the present numerical model. The general characteristics and rules of wind load distributions on arch roofs of stadiums for different conditions are systemically discussed and finally summarized.
