Critical review reveals expanding machine learning roles in structural steel design, indicating that robust physical validation and uncertainty quantification remain essential for safety.

Key Points

Synthesize the application of machine learning across the lifecycle of structural steels—from materials discovery and property prediction to degradation assessment—while evaluating modeling limitations and validation gaps.
Conducted a structured literature review using Web of Science Core Collection and Scopus databases for articles published through July 31, 2026.
Screened and evaluated 110 publications selected for their engineering relevance to structural steels, modeling transparency, and availability of validation data.
Machine learning models have evolved beyond mechanical property prediction to support inverse alloy design, manufacturing process optimization, and prognostics for fatigue, fracture, and corrosion.
Model accuracy and generalization depend substantially on data modality, feature engineering, and cross-dataset validation rather than the specific choice of algorithm.
Independent production-scale validation, uncertainty quantification, and domain applicability assessments remain consistently lacking across durability-critical applications.
