the von Mises stresses at the maximum stressed fibers at the top and bottom
flanges at midspan exceeded the measured yield stresses. In Figure 6.5 , the
stress (principal stresses in direction 1-1) contours at failure of the small-scale
built-up I-section plate girder T1 are plotted. It can be seen that the yield
stresses were reached at midspan in the upper (compressive stresses with neg-
ative sign) and lower flanges (tensile stresses with positive sign). In addition,
in Figure 6.6 , the plastic strain (principal strains in direction 1-1) contours at
failure of the small-scale built-up I-section plate girder T1 are plotted. It can
