SDC Verifier supports tubular connection verification according to ISO 19902, 2nd Edition (2020), Chapter 14.
The implementation works with connections recognized directly from the FE model. Using Connection Finder, SDC Verifier identifies chords and braces together with their geometry and uses this data in the joint-strength calculation.
Brace classification determines whether each brace is treated as a K, TY, or Cross joint. The verification also uses material properties, axial forces, bending moments, brace effective lengths, and chord geometry, including chord cans where applicable.
The implementation also supports overlapping joints, including the additional shear, axial force, and combined loading checks required for these connection configurations.
This keeps tubular joint verification tied to the structural model instead of requiring engineers to recreate individual joints separately for code calculations.
What this implementation checks
- Tubular joint strength according to ISO 19902 Chapter 14
- K, TY, and Cross joint configurations based on brace classification
- Axial forces and bending moments acting on recognized braces
- Chord and brace geometry identified from the FE model
- Chord can effects where the applicable ISO 19902 provisions apply
- Brace effective lengths in local Y and Z directions using beam member data
- Critical joints based on the required minimum brace capacity criteria
- Overlapping joints, including additional shear and combined loading checks
- Material strength properties used directly in the connection calculations
