In this paper, it is proposed an evaluation method for crack width of reinforced concrete members caused by drying shrinkage. The proposed method can be divided into two analyses. One is evaluation for crack interval by solving a differential equation for bond-slip characteristics of one-dimensional RC member, and the other is 2-dimensional non-linear finite element analysis using smeared crack model. This evaluation method is applied to two cracking tests, and it is confirmed whether it is able to evaluate cracking age and crack width with enough accuracy using this evaluation method.
