THE AI ANGLE
Predicting fire-induced temperatures in protected steel beams

Researchers have developed an automated machine learning framework that rapidly predicts the fire performance and heat transfer of three-sided protected steel beams, completing most assessments in under 60 seconds. Trained on hundreds of automated simulations spanning various beam depths and insulation configurations, the gradient-boosting model achieved a root mean square error of just 1.34°C compared to test data. For engineering faculty, this advance provides an efficient alternative to computationally expensive numerical simulations and parameter-limited analytical equations in structural fire safety design.
