was buckling owing to shear stresses, which occurred in the wider web
panel. The data obtained from ABAQUS [1.29] have shown that the von
Mises stresses at the maximum stressed fibers in the web exceeded the mea-
sured yield stresses.

plotted the stress (principal stresses in direc-
tion 1-1) contours at failure of the small-scale built-up I-section plate girder
T2. It can be seen that the yield stresses were reached at the maximum stres-
ses portions of the web. In addition, in
