- Steel Designa. Say a W12x45 is not safe against rupture, what other design considerations should be explored to increase its capacity and thereby be safe for rupture.b. Say you are to design a tension member using a C-section and found out that no C-section is safe against yielding and rupture. As a designer, what would be your approach to this? Ans. is built up section, please do explain why build up section.Considering the following steel connection. The plates in Pink are 9mm steel plates. The middle plate (Yellow) is 18mm thick. The width of the plate is 100mm. The maximum allowable tension stresses on any of the plates is 100Mpa in Gross Area Yielding and 150 Mpa for Net Area or Tension Rupture. The bolts used are 8mm in diameter, the holes are 10mm in diameter, no need to add 1.6mm. The bolts allow a maximum of 280 Mpa of shear. Determine the maximum allowable "P" of the connection in kN.1.10-4 Lateral bracing for an elevated pedestrian walkway is shown in the figure part a. The thickness of the clevis plate - 16 mm and the thickness of the gusset plate - 20 mm (see figure part b). The maximum force in the diagonal bracing is expected to be F 190 kN. If the allowable shear stress in the pin is 90 MPa and the allowable bearing stress between the pin and both the clevis and gusset plates is 150 MPa, what is the minimum required diameter dmin of the pin?
