cannot be mistaken for the result of a numerical analysis, but overall, the set of predictions can be used to derive fragility curves within the input parameter space. Hence, the ML-taxonomy-based is designed for large-scale analysis providing a quantitative measure of fragility under different hazards, to be used for supporting transportation management authorities in the task of prioritizing bridge portfolios.
