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 dy=441 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= 83 mm, b=48 mm, a=12 mm, H=83 mm, d= 48 mm

Question
Question 4 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=441 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= 83 mm, b=48 mm, a=12 mm, H-83 mm, d= 48 mm Z H b h Z d H
