Cover Story (view full-size image): Guaranteeing adequate safety levels in critical infrastructures such as bridges is essential to modern societies and their vital services. Bridges with reinforced concrete structures are subject to deterioration, mostly due to corrosion effects. Gerber saddles are among the critical components of bridges that are particularly exposed to environmental actions. In this study, a framework for the durability analysis of these components is used to perform nonlinear numerical simulations, considering both permanent loads and chlorides attack due to de-icing salt. Thus, Gerber saddles of the iconic Musmeci bridge located in Potenza (Italy) were studied. Durability analyses allowed predicting the corrosion progress and evaluating the saddles’ structural efficiency presently and after fifty years, as a function of chloride corrosion parameters.
