Service life prediction of corrosion-affected reinforced concrete columns based on time-dependent reliability analysis

Reinforced concrete columns in chloride-laden environments are prone to steel reinforcement corrosion, which reduces their capacity to resist applied loads. The current study modeled the time-dependent effect of corrosion as a non-stationary Gaussian process while accounting for the uncertainties of other parameters using random variables. The down-crossing rate of the residual capacity of these structures under combined axial loads and bending...
