摘    要:以某实际结构工程为背景,在同济大学的TJ-3大气边界层风洞中对26个倒伞形挑篷群体结构进行了测压试验,得到了挑篷群上的平均风压系数、脉动风压系数、典型风向角下的分块体型系数和倾覆力矩系数,讨论了挑篷上表面、下表面和净风压的风压分布特性和最不利风向,并分析了挑篷间的相互气动干扰效应.结果表明,挑篷上的风荷载主要以向上的合...

关 键 词:倒伞形  风洞试验  体型系数  干扰效应  倾覆力矩

Abstract:Based on an actual structural project,a wind tunnel test of 26 inverted umbrella-shape structures was carried out in TJ-3 boundary layer wind tunnel in Tongji University.The wind loads on the structures(canopies)were analyzed in detail according to the test results,such as the mean and root-mean-square(rms)pressure coefficients,area shape coefficients and overturning moment coefficients in some typical wind directions.The wind pressure distribution characteristic on the upper and lower surfaces and the net ...
Keywords:inverted umbrella-shape  wind tunnel test  shape coefficient  interference effect  overturning moment
