摘    要:在TJ-2大气边界层风洞中,利用同步测量技术对底部开敞和封闭的鞍型索网屋盖在B类和D类风场条件下进行了刚性模型风洞测压试验.根据风洞试验结果,分析了两类风场条件下这两类鞍型索网屋盖上的体型系数的分布规律及相互关系,并通过对开敞和封闭的鞍型屋盖表面体型系数的对比分析,考察了底部开敞对鞍型屋盖风压分布特性的影响规律.

关 键 词:鞍型屋盖  风洞试验  风压特性  体型系数

Abstract:The wind tunnel tests on rigid models of saddle shape cable roofs with or without enclosed wall were carried out in exposure categories B and D in TJ2 wind tunnel by using the synchronous multi pressure scanning technique. The mean wind pressure coefficient (shape factor) were investigated based on the wind pressure data obtained from the test.The distribution characteristics of the shape factors on the two wind field conditions and their relationships were specially analyzed. Besides, the influences from the enclosed wall on wind pressure distribution characteristics were also discussed in detail in comparison with the shape factors on the saddle roof model with or without enclosed wall.
Keywords:saddle roof   wind tunnel test   wind pressure   shape factor
