to 200 ton loads. The size of test Specimen Fig. 27 General View of Photographing 
of the wide-flange is JIS. G3192 H-300x150 
(Depth=300 mm, Width=150 mm, Web 
thickness=6.5 mm, Flange thickness=9mm). 
Photo.15 shows the general view of the test 
specimen with the pressure plate, on which a 
special metallurgical finish was applied on both 
sides. Stereo-photographs are taken under 
loading conditions of 0, 60, 100, 110, 120, 130, 
135, 140, 142, 144, 128, 121 and 110 tons. Pressure 
loading decreases artificially after 110 tons and 
drops to the last condition where the pressure 
needle shows the zero-reading. Under this 
  
condition, a pair of photographs are taken again as

the stereo-model. For easily taking measure- 
ments of the surface of specimens, white grid lines of 2. 4 cm were painted in both 
longitudinal and lateral directions for determining the measurement points. 
3.2.3 Results of Measurement 
Several pairs of photographs under loading conditions of 0, 144, 128, 110 tons 
and the last 0 ton are selected for the measurement of deformation at the intersection 
pts. of the grid. Especially for the central parts where the maximum deformation 
occurred a loading-deformation diagram was completed to form X-Y, Y-Z and 
X-Z planes. Photo. 16-18 show the general view of deforming of the wide flange under
