plotted. It can be seen that the plastic strains were concentrated at midspan in
the concrete (compressive strains with negative sign) and lower steel plate
girder flange (tensile strains with positive sign). Furthermore, in

,
the von Mises yield stress contours at failure of the composite plate girder G1
are plotted. It can be seen that the yield stresses were reached at midspan in
the lower flange of the steel plate girder. The load-midspan deflection curves
predicted experimentally and numerically were compared as shown in
