This study aims to investigate the deterioration of the seismic performance of massive Reinforced Concrete (RC) wall structures due to restrained shrinkage cracking, which inevitably occurs and affects the overall performance of concrete. (RBSM) and Truss-Network Model (TNM) that could easily reproduce cracking behavior and mass transport in concrete, respectively. Regarding crack distribution and load-deformation relationship, the mechanism of restrained shrinkage cracking and its effect on structural performance was clarified.
