Implication

This analysis reveals that accounting for component correlation in bridge seismic reliability significantly alters damage predictions and improves computational efficiency.

Key Points

This research aims to improve the seismic reliability analysis of reinforced concrete arch bridges by accounting for component correlations.
Developed a seismic reliability analysis method utilizing the D-vine Copula function.
Obtained seismic vulnerability curves and hazard curves for key components of the arch bridges.
Used maximum likelihood estimation to select optimal Pair-Copula functions for correlation analysis.
Damage probabilities ranked arch ring highest, followed by piers, main girder, and lowest for columns.
Considering component correlation reduced seismic reliability indices for various damage states, indicating overestimation when ignored.
D-vine Copula method showed strong agreement with Monte Carlo results, improving computational efficiency by over 80%.
