    Easy to Use

    Beam Member Finder auto-detects member lengths and cross-sections, saving hours of manual setup.

    Professional Reports

    Get structured output with all limit state evaluations and section checks, formatted for internal or regulatory review.

    About Standard

      SDC Verifier

    The Architectural Institute of Japan (AIJ) standard for steel structures — officially titled Design Standard for Steel Structures Based on Allowable Stress Concept — defines the foundational rules for stress-based verification of structural steel components.

    Originally influenced by the AISC standards from the 1960s, AIJ-ASD 05 uses unfactored loads and elastic analysis to check member strength under normal and seismic conditions. It supports both rolled and welded sections.

    This standard is mandatory for moderate earthquake loads and commonly used for buildings, industrial frames, and other steel structures throughout Japan.

    SDC Verifier implements full beam member checks for common shapes: I-beams, channels, T-sections, tubes, and solid bars — with support for slenderness ratio checks, net section reductions, and material strength assumptions per Chapter 5.1.

    Frequently Asked Questions

    Which version of the AIJ standard is implemented in SDC Verifier?

    SDC Verifier supports AIJ-ASD 05, also known as AIJ 2017, based on the 2005 edition of the Design Standard for Steel Structures – Based on Allowable Stress Concept.

    What types of structural members are supported?

    Beam member checks are available for I-beams, Channels, Tees, Circular and Rectangular Tubes, and Circular and Rectangular Bars.

    Can I use automatic recognition for beam lengths?

    Yes. Beam lengths in Y and Z directions are automatically detected using the Beam Member Finder tool. If not recognized, you can trigger recognition manually.

    How are material properties handled?

    You can either define material yield and tensile strength manually or use the properties assigned to materials in your FEA model. The software ensures that all required material data is present before calculation.

    Does SDC Verifier account for additional bending moments in compression members?

    Yes. You can enable an option to consider additional bending due to axial compression and deflection, as defined in the AIJ commentary.

    How is the slenderness ratio limit enforced?

    A maximum slenderness ratio can be specified as per Chapter 11.2 of the standard. The software checks if compression members exceed this limit.
