| 要旨 | In this study, accelerated corrosion tests on three RC beams were carried out. The non-uniform steel corrosion along the corroded rebar and the associated longitudinal crack width of RC beams at various corrosion levels were monitored by X-ray and digital image processing techniques. A three-dimensional (3D) finite element (FE) model was established based on a half ellipses-shape corrosion expansion model to simulate the corrosion-induced crack width distribution. The non-uniform corrosion around the rebar perimeter and along the longitudinal rebar was considered in the 3D FE model. A comparison between the numerical and experimental results was conducted. The 3D FE model provided a good agreement with experimental distribution of corrosion crack width. |
