Question
Transcribed Image Text:The channel shape cross-section and the rectangular cross-section shown in the Figure Q4 are
made of materials with elastic-perfectly plastic behaviour. The yield stress of the material used for
the channel shape cross-section is oy=418 MPa, whereas that used for the rectangular cross-
section is 0.70y.
Compute the thickness of the web, t, of the channel shape section if the two cross sections have
identical plastic bending moment about the z-axis.
In Figure 4, h= 84 mm, b=46 mm, a=11 mm, H=84 mm, d= 46 mm
