Structural reliability analysis of deteriorating RC bridges considering spatial variability

Abstract : This paper proposes an extension of random field theory for modeling spatial variability of deterioration processes, herein, the expansion Karhunen-Loève is used. The studied structure is discretized into several elements and system reliability is used to evaluate the probability of failure. Some considerations for optimal discretization will be also discussed in the paper. The series system methodology will be applied to the reliability analysis of a RC bridge girder placed in a chloride-contaminated environment. The results of this study illustrate the importance of including spatial variability in the problem.
