摘要
Prediction of time-dependent deformation such as shrinkage and creep are of utmost interest in terms of long-term serviceability of a concrete structure. However, owing to highly heterogeneous nature of concrete, existing macroscopic prediction models lack in terms of its general applicability. Hence, in this study, a multi-scale description is used to simulate the shrinkage and creep of concrete where the heterogeneity and associated physical-chemical processes are modeled in a mathematical framework. A hierarchical homogenisation technique is used to link across different scales. Model predicated shrinkage and creep are then validated with the corresponding experimental data. Model prediction is also compared with few national codes and popular macroscopic models to highlights the associated gaps in these models that can be overcome with the present developed multi-scale approach.
