not reached at midspan in the upper (compressive stresses with negative sign)
and lower flanges (tensile stresses with positive sign). In addition, in
Figure 6.31 , the von Mises yield stress contours after the application of
the live load case are plotted. It can be seen that the yield stresses were
not reached at midspan in the upper and lower flanges. The load-midspan
