The Use of Fragility Curves in the Life-Cycle Assessment of Deteriorating Bridge Structures

Within the context of structure deterioration studies, we propose a new numerical method based on use fragility curves. In particular, present work aims to theoretically study degradation concrete bridge structures subjected aggressive environments. A simple probabilistic curves is presented which allows forecasting lifetime considered structural system and best monitoring time. The was applied investigate used as case study. Monte Carlo procedure simulate variation over time residual resistant section ultimate bending moment deck this context, are reliable indicators possible scenarios. comparison with other methods, main advantage proposed approach small amount computing required obtain rapid assessment reliability level structure.
