Hazard-based seismic fragility functions for steel moment-resisting frame buildings through data-driven damage state identification

Key Points

• Seismic fragility functions demonstrate how steel moment-resisting frames respond to earthquake-induced damage states, showing significant variations.
• Key evidence indicates that varying structural parameters affect the fragility, leading to different outcomes in multiple scenarios.
• Assessment through data-driven analysis enhances the understanding of damage states, crucial for effective structural analysis and safety evaluations.
• Highlighting the importance of integrating data-driven methods into seismic design practices, further validation may be required for wider applications.
