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 pared and analyzed.Thus conclusion was drawn for test.
