Methodology
The AISC 360-16 design engine is checked against the AISC Design Examples v15.0 (Companion to the AISC Steel Construction Manual, 15th Edition).
- Resistance Checks: Checked against Chapter D (Tension), E (Compression), F (Flexure), G (Shear), and H (Combined Actions) using LRFD and ASD provisions.
- Section Classification: Automated slenderness checks for stiffened and unstiffened elements according to Table B4.1.
- Interaction: Validation of Equation H1-1a and H1-1b for members under combined axial force and biaxial bending.
Verification Results
Each row compares a calculated result against a published reference value. The difference column shows the percentage deviation.
