It is very difficult to accurately estimate the bond stress of cracked reinforced concrete due to the corrosion of rebar, as there are many factors that affect the bond stress, including corrosion ratio of rebar, speed of electrolysis test, tensile concrete stress, rust transfer, and so on. In this paper, corroded specimens with cracks in the concrete cover were tested, and the method for estimating bond stress is suggested. The data shows that it is feasible to estimate the bond stress based on three major factors: corrosion ratio of rebar, corrosion crack width and tensile concrete stress. |
