Comparison of the seismic fragility of reinforced concrete continuous girder bridges considering near-field and far-field earthquake sequences

Key Points

• Seismic fragility assessment reveals significant variations in performance between near-field and far-field sequences, with implications for bridge safety.
• Key findings indicate a 30% higher fragility index for bridges under near-field earthquake sequences compared to far-field sequences, suggesting more risk.
• Analysis of reinforced concrete continuous girder bridges focuses on structural responses to different seismic inputs, allowing for targeted design modifications.
• The study underscores the need for improved design methods to enhance resilience against specific earthquake conditions, such as near-field effects.
