This paper presents the formulation of a time-dependent seismic fragility format for bridges, as well as new insights into the potential effects of aging and deterioration on seismic vulnerability traditionally neglected in fragility modeling, including joint impacts of multiple component deterioration not investigated to date. The study evaluates the impact of lifetime exposure to chlorides fr...

The purpose of the paper is to describe and compare deterioration and maintenance models for civil infrastructures. These models can be applied to determine the best maintenance strategy to insure an adequate level of safety at minimal life-cycle cost while taking the uncertainties in the deterioration process into account. Without being complete, a time-dependent deterioration process can be m...
