Summary

• What is new: A novel machine learning framework called Domain Knowledge Enhanced Neural Network (DKNN) significantly improves the prediction accuracy of the bearing capacity of CFSTs.
• Why this is important: There’s a gap between traditional engineering methods and machine learning techniques in accurately predicting the bearing capacity of Composite Fiber Steel Tubes (CFSTs).
• What the research proposes: The paper introduces the DKNN model that integrates domain knowledge with advanced feature engineering techniques to predict the bearing capacity of CFSTs more accurately.
• Results: The DKNN model achieved a Mean Absolute Percentage Error (MAPE) reduction of over 50% compared to existing models, proving its robustness and reliability in prediction accuracy.
