| Research Abstract |
In this study, it was estimated the standard drying shrinkage strain of concrete in existing RC buildings based on results of oven dry shrinkage test for the core test pieces. And we studied the estimation method on causes of crack in concrete of buildings. From these results, we proposed the methods as follows ;
(1)The testing methods of oven drying shrinkage stain from core test pieces
(2)The estimation methods on drying shrinkage stain considering finishing materials and environmental conditions
(3)The estimation methods on cases of crack in existing RC buildings based on (1) and (2)
