In this study, the 3 point-bending test was performed on the RC T-beam and the image processing method was used to analyze the change of curvature according to the step of loading. As the loading step progressed, the bending deformation and inflection point of curvature by shear cracks occurred. It will be possible to evaluate the detailed behavior of the RC structure by using the image processing method used in this study.
