摘　　要：通过对6×4跨扣件式钢管模板支架结构中心立杆进行垂直加载试验,测量模架中各杆件上所设点的竖向位移,分析立杆的加载对周围杆件变形的影响程度。然后用MATLAB7.0编制程序,绘制中心立杆加载时,其周围杆件的变形曲线,以及模板支架上各测点位移随中心立杆荷载增加而变化的曲线,并对测点位移曲线进行分析比较,从而得出试验结论。Through the test that the upright tube is uploaded verticaUy for the center upright tube in the 6 × 4 span steel tubular formwork support with couplers, survey the vertical displacement of measuring points on the bars in the formwork support, analyze effect for the bar around in the upright tube loading. Then by MATLAB 7.0 programming, draw the deformation curve of the bar around while the center upright tube loading, and draw the displacement curve of measuring points on the formwork support while the center upright tube loading, and the displacement curve of measuring points was compared and analyzed. Thus conclusion was drawn for test.
