The Designing with HSS video series is back. In the latest video, I discuss the various types of connections and the unique challenges involved when designing with hollow structural sections. Check it out.

The following are the top three key takeaways for designing with HSS connections:

  1. The local strength of HSS members is an integral part of HSS connection design
  2. Proper member selection by the EOR will have an effect on HSS connection design
  3. Reinforcing of connections is difficult and expensive and usually not an option due to architectural or fabrication restraints

If you have any ideas for additional topics, or questions about any of the information provided in the series, please let me know at or visit
