- 論文の詳細を見る
This paper deals with the experimental investigation on the effects of the corrosion of reinforcement due to the sodium chloride on the yield strength, the tensile strength and the elongation relating to the fundamental concept of the RC structuire design. The main concluisions are as follows : (1)The long term corrosion rate over four cycles becomes a constant value of about 180 midd. (2)The corrosion degree of round bar is much larger than that of steel plate. Therefore, the covering of the RC members is very important. (3)The tensile strength of reinforcement depends on the"structure-sensitive"property concerning the pitings. (4)The special attention must be paid to the tensile strength, the elongation and the toughness of the reinforcement from the viewpoint of the earthquake-resistant RC structure.
