Atlas TubeAtlas TubeWhere you can use this: Atlas Tube HSS Connections Hub and Calcs.comStatus: Released
The HSS connection calculators in this section run on two platforms. The calculators themselves are the same software. The portal around them is not.

​
Which one are you on?

Both are built by Calcs.com. The Connections Hub is the Atlas Tube branded edition, offered free to engineers designing with HSS.

​
What is identical

Everything inside a calculation:
  • The calculation engine, the equations and the code references
  • Inputs, presets and connection configurations
  • Limit states and how utilisation is reported
  • The live connection diagram
  • Load combination generation and ASD or LRFD handling
An article about a calculator applies to you whichever platform you are on, as long as that calculator is listed as available to you. That is what the box at the top of every page tells you.

​
What differs

​
Reading the availability box

Every page in this section opens with a box like this one:
Where you can use this: Atlas Tube HSS Connections Hub and Calcs.comStatus: Beta · Region: US · Design codes: AISC 360-22
Where you can use this lists the platforms the feature is live on, each linking to that platform’s sign-in page. If only one is listed, the feature is not available on the other yet. Status is one of: Region is the building standard the calculator is written to. Design codes lists the standards it references.
Beta means the calculation runs and the limit states are implemented, not that the numbers have completed validation. On a beta calculator, verify governing results independently before issuing.

​
A calculator I need is not available on my platform

Calculators reach the two platforms at different times, usually Connections Hub first for HSS connections. If a calculator you need is listed as Connections Hub only, a free Connections Hub account gets you access to it today.
