ABSTRACT
In this paper, the deterioration of existing structures is analyzed considering the model developed by the authors (Neves and Frangopol 2005). In this model, the performance of structures is defined in terms of lifetime probabilistic condition, safety, and cost profiles. The main advantages of this model are the ability to consider the entire performance history of the structure, including deterioration and effects of maintenance actions as well as the ability to combine common performance indicators, namely the condition index, with more consistent indicators, such as the safety index.
