| 要旨 |
The overall time development of drying shrinkage of concrete can usually be predicted with reasonable accuracy by using the currently existing prediction formulas such as ACI, B3, CEB 1990, GL 2000 and JSCE models. However, they are not sufficient when the drying condition is complex and the local strain value is needed. Therefore, in this study, a numerical model approach is investigated. This numerical model includes some model parameters to be determined. These parameters are estimated by comparison between calculation results by prediction formulas and those by the present numerical model.
