This paper investigates the influence of the environmental aggressiveness and exposure scenario on the life-cycle seismic performance of reinforced concrete frames under chloride-induced corrosion. Chloride ingress and corrosion damage are described at cross-sectional level by two-dimensional concentration maps and damage indices. The seismic capacity of the deteriorating structure is evaluated by means of time-variant pushover analyses over the structural lifetime. The uncertainties are taken into account in probabilistic terms by Monte Carlo simulation. The procedure is applied to life-cycle seismic assessment of a three-storey frame under different exposure scenarios defined by varying both the concentration level and the spatial distribution of chlorides on the external surface of the structural members.

Abstract

This paper investigates the influence of the environmental aggressiveness and exposure scenario on the life-cycle seismic performance of reinforced concrete frames under chloride-induced corrosion. Chloride ingress and corrosion damage are described at cross-sectional level by two-dimensional concentration maps and damage indices. The seismic capacity of the deteriorating structure is evaluated by means of time-variant pushover analyses over the structural lifetime. The uncertainties are taken into account in probabilistic terms by Monte Carlo simulation. The procedure is applied to life-cycle seismic assessment of a three-storey frame under different exposure scenarios defined by varying both the concentration level and the spatial distribution of chlorides on the external surface of the structural members.
