Abstract: Probabilistic methods of structural safety are being widely accepted as a basis for rationally considering uncertainties and developing reliability based design specifications for various structures. With public emphasis shifting to conserving the present infrastructure, structural evaluation strategies are now gaining wide importance. It is therefore natural to apply similar reliability techniques to evaluation. This paper explores important differences in evaluations as compared to design and highlights these differences using highway bridges as an example.
