API RP 2A-LRFD Connections (2019)

SDC Verifier supports tubular connection verification according to API RP 2A-LRFD, 2nd Edition, November 2019, 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, brace effective lengths, axial forces, bending moments, and chord geometry, including chord cans where applicable.

This keeps tubular joint verification connected to the structural model instead of requiring engineers to recreate individual joints separately for code checks.

What this implementation checks

• Tubular joint strength according to API RP 2A-LRFD Chapter 14
• K, TY, and Cross joint configurations based on automatic brace classification
• Axial forces and bending moments acting on recognized braces
• Chord and brace geometry identified from the FE model
• Chord can effects for applicable Y- and X-joints
• Brace effective lengths in local Y and Z directions using beam member data
• Critical joints according to the applicable API RP 2A-LRFD provisions
• Material strength properties used directly in the connection calculation
