There is a common misconception that structures using hollow structural sections (HSS) are more expensive than those comprised primarily of open sections. The truth of the matter is that it is in the fabrication of HSS where costs can creep up, far more than the cost of the actual steel itself. So proper HSS member design and connections have a significant influence on the total fabricated cost of a structure. The Steel Tube Institute (STI) went directly to fabricators to learn how to reduce the costs of HSS fabrication and connections. This SE University presentation shared those insights, helping engineers to learn what fabricators wish they knew about HSS.
