Life-cycle seismic fragility of bridge considering corrosion

Time-dependent seismic resilience of aging structures.

This study proposed a seismic emergency performance optimization model for infrastructure systems under demand differences. The model considered different seismic intensities, aiming at maximizing the effects of resilience enhancement measures to meet the expected performance of residents within the resource constraints. In addition, the model set the baseline for the optimization results by means of three functionality variables in earthquake scenarios.
