CFST–CFRP Structural Performance Dataset

A curated dataset of Concrete-Filled Steel Tube (CFST) beams strengthened with Carbon Fiber Reinforced Polymer (CFRP), compiled to support the research article:

Physics-Informed Data Augmentation for Explainable ML-Based Multi-Objective Optimization in Flexural Design of CFRP-Strengthened CFST Beams Muluken Bogale, Addisu Mengistu, Tariku Habtamu Structures (Elsevier), 2025

This dataset provides geometric, material, CFRP strengthening configuration, and flexural performance (Mu) parameters used for ML modeling and physics-informed data augmentation.

Dataset Summary

This dataset contains structural parameters and experimental flexural capacity of CFRP-strengthened CFST beams. It is designed for:

  • Structural engineering ML modeling
  • Physics-informed learning
  • Flexural strength prediction
  • Optimization (material usage, constructability, performance)
