Probabilistic Finite Element Method for the evaluation of ASR affected concrete structures

Alkali-silica reaction (ASR) in concrete can induce degradation in its mechanical properties, leading to compromised serviceability and even loss in load capacity of concrete structures. Dams and bridges have been reported to be affected by ASR which lead to expensive mitigation operations as well as demolishing of the structure in Canada and Australia. This research aims at providing reliable evaluation procedures on ASR affected concrete structures in terms of their health condition and load carrying capacity. The specific objectives of this study are (1) to reduce uncertainties and provide better approach for estimation of mechanical properties degradation and evaluation of damage level due to ASR, and (2) to develop a probabilistic based finite element model integrated with Bayesian updating for uncertainty quantification and propagation to identify ASR effects, and evaluate structural behavior, and load capacity of ASR affected concrete structures.
