Performance-based seismic evaluation and machine learning prediction of damage index for externally strengthened reinforced concrete columns with high-performance fiber composite laminates

Key Points

• Damage index increases with seismic load, emphasizing the importance of proper evaluation methods in construction.
• Machine learning accurately predicts damage index with an R-squared value of 0.85 during testing.
• Assessment using performance-based seismic evaluation reveals insights on reinforced concrete and composite materials.
• Highlights the need for improved frameworks in evaluating structural integrity during seismic events.
