[提要] 利用風(fēng)洞試驗(yàn)測量篷布等柔性材料圍護(hù)結(jié)構(gòu)受風(fēng)載作用時產(chǎn)生的集中力,給出了模型集中力系數(shù)隨風(fēng)向角的變化曲線及集中力大小和方向的算法,重復(fù)性試驗(yàn)表明,試驗(yàn)數(shù)據(jù)可靠。對比試驗(yàn)分析了剛性及柔性材料模型的壓力系數(shù)。提供了柔性材料受風(fēng)載作用時集中力的測量方法,為此類結(jié)構(gòu)的設(shè)計(jì)提供了依據(jù)。
[關(guān)鍵詞] 柔性材料 圍護(hù)結(jié)構(gòu) 風(fēng)洞試驗(yàn) 集中力How to gauge the concentrated force of enclosure of flexible materials as cloths bearing the wind load through tunnel test is discussed. The test results give the curves of the coefficient of concentrated force with the angle of wind and the way to get the value and direction of concentrated force. The repeated test proves that the test data are reliable. The coefficient of wind pressure of rigid and flexible material models are tested in contrast.A new way to measure the concentrated force of flexible materials undertaking the wind load and the basis of structure design is provided.
