Buckling Checks in SDC Verifier

What can SDC Verifier do for you?

  SDC Verifier

Buckling checks are essential for ensuring the stability of structural elements under compressive, shear, or combined loads. SDC Verifier automates the identification of plates and members and verifies their resistance to local and global buckling, following international standards. From thin-walled panels to offshore lattice structures, the software evaluates stability margins and highlights areas at risk of failure.

How Buckling Analysis Is Carried Out in SDC Verifier

    Automatic Plate Recognition

    Panel Finder automatically detects flat plate sections and their dimensions for buckling evaluation.

    Stress Direction Conversion

    Stresses are converted into plate-local directions for accurate buckling factor computation.

    Cross-Section Classification

    Cross-section parts (webs, flanges) are categorized to determine structural behavior under load.

    Standards-Based Buckling Checks

    Validate buckling using ABS, DNV, Eurocode 3 (EN 1993-1-5), AISC 360, ISO 19902, API RP-2A, and NORSOK N004.

    Automated Reporting

    Detailed buckling reports are generated automatically for each load case — with full traceability.
