Outline of Final Research Achievements

The purpose of this study is "Accuracy improvement of the crack prediction method of concrete" and "Proposal of a simple analysis method of the crack prediction". The CP method is a popular crack prediction method. Because the CP method can treat three dimensional analyses by two dimensions. However, the previous CP method was not able to consider the autogeneous shrinkage, the drying shrinkage, and the effect of expansive materials.
Therefor the CP method was improved, and a calculation including these was enabled. In addition, the system that predict the crack from the construction data that had been accumulated in the past was constructed.
