Recent Progress in Research on and Code Evaluation of Concrete Creep and Shrinkage in Japan

This paper introduces the recent state of research on creep and shrinkage of concrete in Japan, focusing on several unique advances: new prediction models in design code, development of database, autogenous shrinkage and prediction of cracks in structural members. New prediction models for creep and shrinkage of concrete, which can be applied to high-strength concrete, were adopted in the JSCE standard specification for concrete structures in 2002. A creep and shrinkage database was developed and made available for international use. Thus Japanese researchers can be said to have made important contributions to research on autogenous shrinkage of concrete in the last ten years.
