Determine the lightest channel section to the given service load;

 

PLL = 900 kN

PDL = 500 kN

 

Use LRFD and NSCP-AISC specifications for the design. The length of the member is 9m. Use A992 steel for both the plate and the section, and D16mm bolts, oversized hole diameter. Assume U = 0.85 for design and analysis. 

  • Determine the governing load combination using LRFD.
  • Determine the lightest channel sufficient to carry the loads.
  • Check the adequacy in terms of strength (Gross section yielding, Tensile rupture strength and block shear)) and stability (slenderness).
