The influence of reinforcement corrosion on shear strength capacity of reinforced concrete (RC) beams was discussed based on the experimental results obtained by the loading tests. The reinforcing bars in concrete were artificially corroded by electrical method means prior to the loading test. It was found that shear strength capacity of the beams contributed by web reinforcement decreases, with the increase of corrosion rate, but that the contribution of concrete to shear strength capacity increases.
Cracking induced by steel corrosion causes the failure mode change. The failure mode change the specimens; shear-tension type to shear-compression type, was observed by using the Image based-measurement system developed by the authors.
