Abstract

This study aims at evaluating shrinkage cracking risk in reinforced concrete structures, which has not been established in the past studies. To achieve this goal, analytical scheme capable of calculating the probability of shrinkage cracking was proposed. In this scheme, the variation of shrinkage restrained stress, that of concrete cracking strength, and safety factor are to be determined. The first two were determined with simple analytical simulation of structural elements, and the last factor was based on the comparison between cracking record of actual RC member and analysis results. Finally, this scheme was applied to actual construction project, and its validity was confirmed during the construction process.
