| Outline of Final Research Achievements |
The objective of this study is to evaluate the contribution of shrinkage and creep of concrete on life of concrete subjected to sustained loading by using the digital image-correlation method. The high-speed image correlation algorism for concrete fracture was developed. The stress caused by shrinkage of mortar was calculated based on thick cylinder theory and strain measured by using the digital image-correlation method. Then, the effect of the stress on the cracking load of mortar was evaluated. In addition, the digital image-correlation method evaluated the area where the minimum principle strain was occurred drastically in the loaded PC beam with diagonal cracks.
