Collapse Fragility Analysis of Non-Seismically Designed Bridge Columns Retrofitted with FRP Composites
The seismic fragility assessment of the bridge can be analyzed using fragility curves which is a method to estimate the probability of damage of the structure at a specific level of ground motion or an intensity measure (IM). The columns are the most vulnerable structural element in the bridges which have a significant contribution to the failure probability of the bridge system. This research presents the collapse fragility curves of non-seismically designed circular reinforced concrete (RC) bridge columns using different combination of parameters located in Vancouver, British Columbia, Canada. Probabilistic seismic demand models are produced using the results obtained from the incremental dynamic analyses. Considering collapse drift as a demand parameter, fragility curves are generated with different parameters of non-seismically designed circular RC bridge columns. It is observed that amount of reinforcement, shear span-depth ratio, and axial load are significantly affect the collapse fragility curve of the retrofitted bridge columns.
