# Calculators

> Every calculator in the Atlas Tube HSS Connections Hub, by connection family and region, with a link to its guide.

Every calculator in the Connections Hub, grouped by connection family and then by region. Where a guide exists, the calculator name links to it. **Coming soon** means the calculator is available but its guide has not been written yet.

> **[General HSS Truss Connection (T, K, Y, X, KT)](https://calcs.com/docs/partners/atlastube/calculators/truss/us/hss-truss-connection.md)**
>
> Auto-classify and design HSS truss joints, including gapped and overlapped KT, to AISC 360-22 and Design Guide 24.

> **[Column Bracing Connection: Double Gusset Configurations](https://calcs.com/docs/partners/atlastube/calculators/bracing/us/column-bracing-double-gusset.md)**
>
> Design internal and external double gusset brace connections, where the brace force is split between two gusset plates.

> **[HSS Steel Base Plate](https://calcs.com/docs/partners/atlastube/calculators/base-plates/us/hss-base-plate.md)**
>
> Design HSS column base plates for compression, uplift and brace loading, with anchor rod, concrete breakout and weld checks.

### HSS to HSS

> **[HSS Beam to HSS Girder Shear Connection](https://calcs.com/docs/partners/atlastube/calculators/hss-to-hss/us/hss-beam-to-hss-girder-shear.md)**

### Splices

> **[HSS to HSS Splice Connection (End Plate)](https://calcs.com/docs/partners/atlastube/calculators/splices/us/hss-to-hss-splice-end-plate.md)**
>
> Design bolted end plate column splices between HSS members for axial, moment and shear, with AISC 341-22 seismic capacity design checks.

> **[HSS to HSS Splice Gusset Connection (Shuriken)](https://calcs.com/docs/partners/atlastube/calculators/splices/us/hss-to-hss-splice-gusset.md)**
>
> Design a bolted round HSS column splice using four shop-welded gusset plates and field-bolted splice plates, to AISC 360-22.

### Composite

> **[WF Beam to Concrete-Filled HSS Moment Connection](https://calcs.com/docs/partners/atlastube/calculators/composite/us/wf-to-concrete-filled-hss-moment.md)**
