Key Points

The aim is to develop a reliable model for predicting progressive collapse resistance of reinforced concrete beam-column substructures using advanced machine learning techniques.
Established a high-quality dataset with 10-dimensional features related to compressive and tensile actions during progressive collapse.
Compared performances of three machine learning models: random forest, least square boosting, and generalized additive models.
Utilized a particle swarm optimization algorithm to refine model parameters and applied Shapley analysis for prediction insight.
PSO-RF model achieved the highest prediction accuracy during compressive and tensile action stages.
Significant prediction factors identified include span-to-height ratio and cross-sectional area.
Proposed model outperformed traditional physical models, emphasizing its potential for updating RC structural codes.
