N2 - An approach to evaluate the structural reliability taking into account the degradation of the structural capacity due to corrosion of reinforced concrete buildings at the end of a time interval is proposed. The structural reliability is expressed in terms of the confidence factor, within a Demand and Capacity Factor Design format (DCFD). A new closed-form mathematical expression that considers the non-linear structural capacity degradation due to corrosion by means of a second degree polynomial function is developed. The confidence factors are obtained under the assumption that the structural capacity degradation due to corrosion follows a linear and non-linear function over a time interval. The structural reliability is obtained for a three-story reinforced concrete building subjected to two sets of real seismic ground motions recorded in Acapulco Bay Mexico. Both, aleatory and epistemic uncertainties are taken into account into the analysis. A maximum difference of 3.5% between both functions after 83 years from the construction of the building was found.
