Webinars On Demand: What Your Fabricator Wishes You Knew About HSS




There is a common misconception that structures using hollow structural sections (HSS) are more expensive than those comprised primarily of open sections even though HSS sections are often more geometrically economical – mainly due to the difference in cost on a unit weight basis. HSS member design and connections have a significant influence on the total fabricated cost of a structure. The Steel Tube Institute has conducted surveys and focus groups with fabricators to learn how to reduce the costs of HSS connections. Attendees of this presentation will learn which details work (and which don’t); what you need to know about HSS in AESS applications; tolerances and how to detail for them; and relative costs of HSS fabrication.

Learning objectives include:

  • the relative cost differences of WF beam to HSS column shear connections.
  • the relative costs of WF beam to HSS column moment connections.
  • how to best specify cost efficient HSS trusses.
  • how the weld seam should be handled in an AESS application.
