OmegaBuckling

Overview

Section-based buckling capacity prediction of rack uprights using machine learning.

OmegaBuckling is an advanced machine learning-based tool for predicting the axial buckling capacity of cold-formed steel uprights used in storage rack systems. Developed from a rigorously validated dataset derived from experimental and numerical analyses, OmegaBuckling provides accurate estimations of critical buckling load based on geometric and material properties of rack sections.

The underlying model is based on a peer-reviewed scientific study published in a high-reputation academic journal, ensuring transparency, credibility, and engineering-grade accuracy for structural professionals and researchers alike.

This software predicts the buckling capacity of structural rack uprights based on data reflecting collapse-stage loading. Estimated capacities represent critical loads under idealized conditions.

All design decisions, safety factors, and regulatory checks must be independently evaluated and applied by the practicing engineer. The authors and developers assume no liability for misuse or misinterpretation.
