英文摘要
To clarify the relationship between steel corrosion and cracks in RC members subjected to cyclic loading, influencing factors affecting steel corrosion were examined. Focusing on the loading condition and cracking condition in actual structures, measurement of crack width near reinforcing bars and accelerated steel corrosion tests were carried out. As results, crack width near reinforcing bars and bond degradation length increased as the cover length exceed particular threshold value. Steel corrosion may initiate earlier despite of having larger cover thickness. It was clarified that crack width near reinforcing bars may be the important factor on steel corrosion.
