Abstract: In practice, short discrete fibres in concrete can effectively reduce the cracking potential of concrete caused by the restrained shrinkage. In the present study, a fracture mechanics-based numerical model was developed to predict the cracking of fibre reinforced concrete rings in restrained shrinkage test tailored for assessing cracking potential of fibre reinforced concrete. With the proposed model, some remarkable features on the shrinkage cracking such as the age of crack initiation and crack evolution process can be predicted accurately, as well as the crack width for plain and fibre-reinforced concretes. The findings are helpful to move forward the ring test from an index test to be more meaningful that potentially provides quantitative results for interpreting cracking of restrained concrete in the field.
