Outline of Final Research Achievements

In this study, I have developed camera type full-field strain measurement device (camera device) . Then, it was confirmed measurement accuracy of strain and displacement of the camera device. It was studied image processing technique for the measurement accuracy.It was developed existing action stress estimation program. It was investigated the accuracy of existing action stress estimated using no curvature concrete member.
