| Outline of Final Research Achievements |
Since 3-D Finite Element Method is developing with computer progress, we are able to acquire a huge amount of computational result. On the other hand, it is not satisfactory to measure strain distribution in the high spatial resolution and accuracy. Therefore verification method between computational results and experiment should be improved for efficient validation. In this study, 1) the prototype development of displacement and strain field measurement system for wide region based on divided image acquisition, 2) the field verification by real size building experiment at E-defense, are performed. We achieved the planned detection accuracy of strain smaller than 0.1%, and gained perspective to improve the system by faster mirror movement and larger aperture lens utilization.
