API RP 2A-LRFD Connections (1st, 1993)

The API RP 2A-LRFD Connections (1st, 1993) implementation in SDC Verifier verifies the strength of tubular connections according to Section E of the standard. It evaluates recognized chords and braces directly in the FEA workflow, including checks for axial force, bending moment, and their interaction at the joint level. 

Using Connection Finder, SDC Verifier automatically identifies supported connection geometry and extracts the chord and brace parameters required for calculation. The implementation uses defined yield and tensile material properties and applies the relevant connection equations inside the model workflow instead of moving the verification into separate manual calculations. 

What this implementation checks 

• Joint axial and bending strength for tubular connections 
• Interaction of brace axial force with in-plane and out-of-plane bending 
• Ultimate joint capacities using API RP 2A-LRFD Section E equations 
• Load transfer for applicable joints with chord cans 
• Overlapping joint checks, including weld-related resistance and perpendicular brace force conditions
