Life-cycle seismic performance analysis of an offshore small-to-medium span bridge based on interpretable machine learning

In earthquake-prone offshore regions, small-to-medium-span bridges undergo significant deterioration in seismic performance due to chloride corrosion and aging impact over their service life. To address this concern, this paper proposes an interpretable machine-learning framework to assess the life-cycle seismic performance of offshore small-to-medium-span bridges. First, the time series on aging features, based on the chloride erosion model …
