Re: HSS to HSS moment connection

Ken:

I designed the Butterfly House in St. Louis using an internal weld
back tube for full-pen welds around all four sides of the tube section.
The back-tube is retractable with a screwed handle in a slot that cut
out from the main tube. You can locate the slot on top of the main tube
 for it not to be seen. The screwed handle can be attached to the back-tube
after the back-tube is slide in the main tube. There is a detail in the
Modern Steel Construction Magazine, June 1999 issue under the article of
Sophia M. Sachs Butterfly House & Education Center. This detail worked
very well in my project. I wish it will work well for your situation as
well.
In case you can not find that MSC issue, please let know your fax number
privately.
I will be happy to fax you a copy.
