摘　　要：文章模拟风载荷下玻璃幕墙的承压情况,采用三维数字照相量测方法,对不同风荷载下玻璃的应变及挠度数据进行采集,并与电阻应变片获得的数据进行分析比较。结果显示:在相同风荷载作用下,同一测点两种方法测得的应变值和挠度值的相对误差较小;两种方法绘制出的应变-位置曲线和挠度位置曲线基本重合。三维数字照相量测方法适用于玻璃幕墙表面应变及挠度量测。This article simulates the force bearing condition of glass curtain wall under wind load;uses threedimensional digital photogrammetry method to collect the strain and deflection data of glass under different wind loads,which is used to be analyzed and compared with the data obtained by the resistance strain gauge.The results show that under the same wind load,the relative error of the strain value and the deflection value measured by the two methods at the same measuring point is small;and the strain-position curve and deflection position curve drawn by the two methods are basically coincide.The three-dimensional digital photogrammetry method is suitable for the surface strain and deflection measurement of glass curtain wall.
