Abstract: This paper presents a numerical study about the effects of chloride-induced corrosion on the service life of structures. A two-dimensional geometrically nonlinear mechanical model based on Finite Element Method (FEM) was developed for reinforced concrete structures. The corrosion initiation stage was evaluated by Fick's diffusion laws. The corrosion propagation was carried out by deterministic models based on Faraday's law. Pitting corrosion was simulated in the reinforcements by pit elements, distributed long… Show more

“…This effect is considered the main cause of building´s deterioration (13). The repairing and maintaining costs due to corrosion-damaged structures can be around 5% of the gross domestic product (14). The rapid screening methods (RSM) evaluate the building´s susceptibility to seismic damage using a seismic vulnerability index (SVI).…”

“…Thus, research on mathematical models that can describe the structural degradation caused by corrosion is increasing. Recent research has explored numerical simulation of chloride diffusion in concrete and reliability analyses based on probabilistic models (Ayinde et al, 2017;Souza and Leonel, 2021;Felix et al, 2020;Ramos and Carrazedo, 2021;Favretto et al, 2021). However, other applications use the finite element method, such as the one proposed by Ramos and Carrazedo (2020).…”
