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.

腐蚀环境下钢筋混凝土桥墩抗震性能评估

本研究研究了腐蚀和地震作用对桥墩的耦合作用。从文献综述开始收集现有的腐蚀模型，然后选择桥梁立交桥进行地震分析。它允许评估由于普遍腐蚀和点蚀而在不同时期降低桥墩的抗震能力。所选的桥梁结构属于高速公路立交桥的类别，是世界各地经常使用的结构系统。因此，开发一种合适且有效的工具来进行此类系统的深入降级分析，并确定最合适的恢复时间，对于保证持续的可维护性和安全性至关重要。
