Abstract
Strain measurement of concrete test pieces was usually performed by using a strain gauge and an embedded strain gauge. But recently, a non-destructive full-field measurement method is strongly required for measurement of complex structures and maintenance management system for structures. A digital image correlation method is a very simply measurement method for the surface deformation using only digital images are taken by a CCD camera. In this study, we will perform the strain measurement of concrete test pieces by using the digital image correlation method to investigate the validity of the optical measurement method.
