Abstract
In this paper, the suitability of digital image correlation (DIC) technology in evaluating the flexural behaviour of as-built and carbon fiber reinforced polymer (CFRP) strengthened reinforced concrete (RC) beams was verified by conducting a 4-point bending test on four large-size beams. The DIC data obtained during the tests were compared to the results measured using traditional techniques such as displacement sensors and electrical strain gauges, as well as the findings derived from finite element (FE) numerical simulations. A good agreement was achieved between the local displacement and strain measurements and the data from DIC as a function of the applied load. Moreover, the crack patterns generated by the FE modelling were validated by the corresponding patterns derived from DIC. This suitability study is expected to contribute to the future field implementation of DIC technology to monitor the CFRP-strengthened members of critical structures such as bridges.
