</Info>

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.

The full [HSS Connections Hub playlist](https://www.youtube.com/playlist?list=PL4r3x1Y99fXb3SpYMXV_8zns76mc4a7Z0) 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.

## What is covered

The calculator library spans the following families. Each has its own article.

| Family     | Calculators                                                                        |
| ---------- | ---------------------------------------------------------------------------------- |
| Shear      | HSS beam to HSS girder shear, HSS to WF shear, WF to HSS shear                     |
| Moment     | HSS to HSS moment (fin plate and stiffened), WF beam to concrete-filled HSS moment |
| Torsion    | HSS to HSS torsion end plate                                                       |
| Splice     | HSS to HSS splice end plate, HSS to HSS splice gusset (Shuriken)                   |
| Truss      | General HSS truss connection (T, K, Y, X, KT)                                      |
| Plate      | Round HSS longitudinal plate, round HSS transverse plate                           |
| Bracing    | Column bracing, internal and external double gusset                                |
| Base plate | HSS steel base plate                                                               |
| Composite  | Concrete-filled HSS column (round, square and rectangular)                         |

<Note>
  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.
