Treatment of and sensitivity to epistemic uncertainty in seismic risk assessment of infrastructures
Seismic risk assessment of an infrastructure, intended as a system of systems including buildings, lifelines and critical facilities, is typically affected by several sources of uncertainty, classified as aleatory or epistemic. Momentum to this work came from the need not only to properly take into account all these uncertainties, but also to provide the confidence in the estimate and quantify the contribution of the employed models and parameters to the total uncertainty.
