be seen that the plastic strains were concentrated at midspan in the upper
(compressive strains with negative sign) and lower flange (tensile strains with
positive sign). Furthermore, in
Figure 6.7
, the von Mises yield stress con-
tours at failure of the small-scale built-up I-section plate girder T1 are plot-
ted. It can be seen that the yield stresses were reached at midspan in the upper
and lower flanges. The load-midspan deflection curves predicted experi-
mentally and numerically were also compared as shown in
Figure 6.8
. It can
