STUDIES OF THE COEFFICIENT OF WIND PRESSURE ON THE MODEL OF DOUBLE ROOFING MEMBRANE STRUCTURE BY WIND TUNNEL EXPERIMENT
【摘要】 提供了双坡屋面薄膜结构风洞模型试验的处理方法和实测结果 ,研究了在各种风向角下模型四周封闭和四周敞开时对风压系数的影响 ,同时还计算了突然开孔所引起的屋面风压系数的变化情况。对试验结果进行了总结和分析 ,为薄膜结构抗风设计的理论研究和工程应用提供了可靠的依据
【Abstract】 In this paper, the experimental results on the model of double slope roof membrane structure in the wind tunnel are presented. The differences of coefficient of wind pressure between models with sealing and opening on all sides are compared in all wind directions, and the change in coefficient of wind pressure is discussed when door is opened abruptly. These results are analyzed, and the basic data of wind resistant design of membrane structure and its application are provided.
