This paper presents an experimental study of bond behavior, cracking, and tension stiffening on corroded steel bars in concrete subjected to uniaxial load. The seven cylindrical RC tension members were experienced with various corrosion levels. It was found through test that in low level corrosion the average crack spacing decreases with increasing of corrosion level. Moreover, it concludes that the decreasing of this average crack spacing is attributed to the increasing of bond strength and the decreasing of concrete tensile strength, which is caused by crack forming around corroded bar. |
