Comparison between the Seismic Performance of Integral and Jointed Concrete Bridges

This article presents a probabilistic fragility analysis for two groups of integral and jointed concrete bridges, with varying length and column height. The results show that the integral bridges perform consistently better from a seismic perspective than the jointed bridges. Comparisons are also drawn between the seismic fragility of different geometric configurations. The results show that for integral bridges, the seismic vulnerability increases with an increase in bridge length and decreases with an increase in column height. For the jointed bridge, it was found that geometric variation in column height and bridge length does not significantly affect its seismic vulnerability.
