2019, Reliability Engineering and System SafetyCitation Excerpt :The corrosion is commonly modelled by the reduction in the cross-section area of reinforcement as a function of time and the characteristics of the chlorides (e.g. [8,38]). In some studies, the reinforcement reduction is estimated using a Monte-Carlo simulation to account for the uncertainty in the factors that affect corrosion [98,130]. It is clear that more reliable deterioration models are needed for the analysis and fragility assessment of corroded RC structures under- and over-ground, including large-scale experimental tests.
Effects of SSI and lining corrosion on the seismic vulnerability of shallow circular tunnels
2017, Soil Dynamics and Earthquake EngineeringCitation Excerpt :The strength of the components of any structural system is a time-dependent property varying along the structure’s service life. The structural strength degradation may be attributed to multiple factors such as corrosion, erosion, other forms of chemical deterioration, and fatigue [Melchers and Frangopol, 2008] [45]. In this specific implementation we are concentrated on the effect of corrosion on the reinforcement bars due to the ingress of chlorides, as this is one of the most serious and widespread deterioration mechanisms of reinforced concrete structures.

2017, Procedia EngineeringConsideration of time-evolving capacity distributions and improved degradation models for seismic fragility assessment of aging highway bridges
2016, Reliability Engineering and System SafetyCitation Excerpt :Almost all elements in nature, structural or otherwise, tend to gradually change to lower levels of energy and in the process undergoes spontaneous degradation throughout their service life. Depending on the exposure condition, the deterioration process of highway bridge components may manifest in the form of corrosion, erosion, or other forms of chemical and physical deterioration [46]. Typically the loss of structural strength in aging bridge columns to resist lateral forces during seismic events is primarily attributed to the corrosion deterioration of reinforcing steel bars.
