Abstract:
A series of tests was carried out on reinforced concrete beams, which were deteriorated by the following methods: electrolytic reaction, wet and dry cycling at high emperature, seawater splashing, and exposure to actual marine environments. The difference in corrosion states for the different deterioration methods was examined from the viewpoint of loss in cross-section of reinforcing bars and crack width caused by corrosion. The results of loading tests on the deteriorated beams suggested an apparent relationship between load carrying capacity of the beams and the average cross-sectional loss of reinforcing bars due to corrosion. Remaining load carrying capacity of existing reinforced concrete members damaged by corrosion of reinforcing bars can be evaluated by the proposed relationship.
