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)

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

Design internal and external double gusset brace connections, where the brace force is split between two gusset plates.

HSS Steel Base Plate

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

Design and check shear connections where an HSS beam frames into the side of an HSS girder, to AISC 360-22 and AISC Design Guide 24.

HSS to HSS Moment Connection

Design fin plate and stiffened HSS moment connections, including beams framing into both faces of the column.

HSS to HSS Torsion Connection (End Plate)

Design a bolted end plate connection between an HSS beam and HSS column under shear, torsion and combined loading, to AISC 360-22.

​
Plate to HSS

Round HSS Longitudinal Plate Connection (T, Y, Cross)

Design a plate welded longitudinally to a round HSS chord in T, Y and Cross connections, to AISC 360-22 and Design Guide 24.

Round HSS Transverse Plate Connection

Design an axial plate welded transverse to a round HSS chord in T and Cross connections, to AISC 360-22 and Design Guide 24.

​
Splices

HSS to HSS Splice Connection (End Plate)

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)

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

Design four-bolt extended unstiffened end plate moment connections into concrete-filled HSS columns, thick and thin plate paths, per AISC Design Guide 39.

Concrete-Filled HSS Column

Design round, square and rectangular concrete-filled HSS composite columns to AISC 360-22 and Design Guide 6.
