In this study, an integrated method for evaluating structural performance and durability of RC structures focusing on the interface between materials was developed considering the time-dependent behaviors of the RC structure's constituent materials and the material interaction. As a result, a theory linking individual elements was created by incorporating external environmental force, the non-homogeneity of the concrete, and the time-dependent behavior of the concrete considering various interface surfaces. Furthermore, it was confirmed that qualitative evaluation using this theory is possible by performing experiments on deteriorated structure as a case study.
