Prediction of time-dependent deformations due to creep and shrinkage of concrete is important as they affect the safety and serviceability of reinforced- and prestressed- concrete members. The long-term responses of number of bridge girders have brought to focus the need to revisit the existing models and attempts are being made to develop more rational models. In the present study, applicability of a multiscale model of concrete proposed in literature for predicting creep compliance at different ages is examined. The results obtained suggest that the multiscale modelling is a promising approach for determining the creep properties of concrete.
