The HSS Connections Hub is Atlas Tube’s free platform for designing hollow structural section connections. It is powered by Calcs.com, so the calculators behave the same way as calculators elsewhere on the platform: live inputs, expandable calculations, code references on every line, and exportable reports.
The Hub brings together three things.
Typical details
A library of fabrication-ready connection details in PDF, DWG and Revit (RVT) formats.
Connection calculators
Design and check HSS shear, moment, splice, truss, bracing, base plate and composite column connections to AISC 360-22.
Engineering support
Access to Atlas Tube’s HSS engineering team when a connection falls outside what the calculators cover.
Video introduction
The full HSS Connections Hub playlist on the Zekelman Industries channel carries the walkthroughs, the webinars and the monthly Connection of the Month series. Individual videos are embedded in the articles they relate to.
Who it is for
Structural engineers detailing HSS connections in the United States, working to AISC 360-22, the AISC Steel Construction Manual (16th edition) and the AISC Design Guides, mainly Design Guide 24 for HSS connections. Accounts are complimentary. Sign up at connectionshub.atlastube.com.What is covered
The calculator library spans the following families. Each has its own article.New connections and feature updates are released roughly every two weeks, so this list grows. Articles marked Beta describe calculators that are released but still being validated.
