(principal strains in direction 1-1) contours at failure of the small-scale built-
up I-section plate girder T2 are plotted. It can be seen that the plastic strains
were concentrated at the maximum stresses portions of the web. Further-
more, in
Figure 6.15
,
the von Mises yield stress contours at failure of the
small-scale built-up I-section plate girder T2 are plotted. It can be seen that
the yield stresses were reached at midspan in the upper and lower flanges.
The load-midspan deflection curves predicted experimentally and numeri-
cally were also compared as shown in
Figure 6.16
.
