| Abstract: |
The impact of climate change due to increasing global warming may negatively influence the performance of reinforced concrete (RC} bridges. In addition to being continuously exposed to unfavorable climatic conditions, bridges in India are also prone to earthquake-induced damage. This study provides a methodology for time-dependent seismic resilience assessment of aging highway bridges considering climate change effects. Nonlinear time-history analyses are conducted to develop seismic fragility curves at different points in time. These results are utilized to estimate seismic losses that are combined with recovery models to estimate the functionality and resilience of aging highway bridge considering climate change effects. The results reveal a declining trend in the resilience of the bridge after taking climate change into account, underlining the significance of considering climate change when evaluating the lifetime seismic resilience of older bridges. |
