Verification Methodology

The CSA S16 design engine is rigorously verified against standard industry benchmarks. Our primary verification suites include S-FRAME CSA S16-14 Design Examples and STAAD.Pro CSA S16-19 Verification Manual.

  • Standard Adherence: Logic follows CSA S16:19 (and S16-14) for all member resistance and stability checks.
  • Automated Testing: Over 130 unit tests covering cross-section classification, member capacity, and combined effects.
  • Industry Cross-Check: Results compared against major FEA packages to ensure consistent and reliable design outputs.
