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 σy = 407 MPa, whereas that used or the rectangular cross-section is 0.90 y. 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. n Figure 4, h= 80 mm, b=42 mm, a=11 mm, H=80 mm, d= 42 mm
