Resumen:

A probabilistic criterion proposed by Cornell et al (2002) and extended by Tolentino et al (2012) is used here to study the effect of long-term material degradation due to corrosion of reinforced concrete buildings located in the Pacific Coast of Mexico. The criterion considers, by means of closed form mathematical expressions, the simultaneous variation of the structural capacity and of the structural demand, over time. The structural reliability is represented in terms of two alternative indicators: a) the expected number of failures over a time interval, and b) the confidence factors as functions of time, within a Demand and Capacity Factor Design format. The reliability indicators are extended here in order to take into account the structural deterioration due to corrosion over a time interval. Both, aleatory and epistemic uncertainties are taken into account. The structural reliability is evaluated for a 4-story building subjected to a set of real seismic ground motions recorded in Acapulco Bay, Mexico.
