Structural modelling of ASR-affected concrete: The approach developed in the PAT-ASR project

The Alkali-Silica Reaction is a harmful reaction which can compromise the integrity and capacity of concrete structures. Due to its nature, a multiscale material model has been chosen to perform structural analyses. The model aims to couple the chemical and mechanical effects in order to characterize the affected concrete into the structures, which is considered as an evolving material. The model has been developed in the project Performance Assessment Tool for Alkali-Silica Reaction (PAT-ASR), which started in 2010 at Delft University of Technology and involves collaboration with the Norwegian Public Roads Administration
