The following thesis investigates the use of Digital Image Correlation (DIC) for the measurement of the vertical displacement profile of reinforced concrete beams. Furthermore, this study aims to utilize the DIC-measured displacement profiles of test specimens obtained at given load levels in an inverse analysis procedure for the identification of the flexural stiffness distribution and damage profile of that member. The DIC measurement study consisted of four simply supported reinforced concrete beams subjected to four-point bending. The results of the study show a 10^-2 mm accuracy in comparison to potentiometer measurements. The enclosed inverse analysis procedure was validated using numerical simulations of steel I-beams subjected to four-point bending with induced stiffness reductions along their central span lengths, and then used for the identification of the stiffness of the central span length of the control specimen from the DIC-measurement study.
