AIJ (2005 Edition, 2017)

The AIJ Design Standard for Steel Structures — based on the Allowable Stress Concept — defines structural member strength requirements for Japanese steel buildings. SDC Verifier supports automated checks from this standard, applied to various cross-sections: I-beams, channels, tees, tubes, and bars.

Implemented features include:

• Beam length detection from FEA model geometry
• Support for maximum slenderness ratio limits (Chapter 11.2)
• Optional inclusion of additional bending from axial load–induced deflection (Chapter 6.1 commentary)
• Material strength definitions via Material Characteristic (Chapter 5.1)
• Welded or rolled section settings, and net area adjustments for holes

The standard assumes elastic analysis under unfactored nominal loads, in line with traditional ASD methodology.
