| Popis: | This is the peer reviewed version of the following article: Domaneschi, M, De Gaetano, A, Casas, JR, Cimellaro, GP. Deteriorated seismic capacity assessment of reinforced concrete bridge piers in corrosive environment. Structural Concrete. 2020; 21: 1823– 1838. https://doi.org/10.1002/suco.202000106, which has been published in final form at https://onlinelibrary.wiley.com/doi/abs/10.1002/suco.202000106. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving. The coupled effects of corrosion and earthquake action on bridges piers are investigated in this study. Starting from a literature review to collect existing corrosion models, a bridge overpass is selected to perform seismic analyses. It allows to assess the degrading seismic capacity of the bridge pier at different periods due to general and pitting corrosion. The selected bridge structure belongs to the class of motorway overpass, that is a frequently used structural system all around the world. Consequently, the development of a suitable and effective tool for an in-depth degradation analysis of this type of system, with the identification of the most appropriate time for restoration, is of paramount importance to guarantee continuous serviceability and safety. |
