説明
In the performance-based design for shrinkage cracking in building, the reliable mathematical model for predicting shrinkage and creep strain of concrete is required. It is desirable that the mathematical model is simple and accurate, and every engineer can use it without any difficulties. Then, in this paper, the prediction formula of shrinkage strain of concrete with a normal to high strength concrete was discussed using the test data published in the annual meeting of Architectural Institute of Japan. The proposed model was expressed as the product of two terms; one is the ultimate shrinkage strain that is expressed in terms of the product of three coefficients taking into account of mix proportions, age at drying and relative humidity, the other the time-effect function (the hyperbolic-power type) in which the effect of specimen size is concerned. Moreover, the effects of the kinds of cement, aggregate and admixture were introduced as the correction factors of ultimate shrinkage strain. It was found that the proposed prediction formula can estimate the shrinkage strain more accurately than the other formulas such as JSCE, CEB-FIP1990 and ACI209.
