인장주근의 부식위치 및 형태가 철근 콘크리트 보의 내력성상에 미치는 영향에 관한 연구

Abstract

There are the reasons of deterioration in reinforced concrete structures such as carbonation, rebar corrosion, and cracks. Especially rebar corrosion is the most important reason of deterioration in RC structures. Because rebar corrosion decrease the load bearing capacity of RC structures, it needs to evaluate deterioration of the load bearing capacity of structural members due to rebar corrosion. So, this study checked up deterioration in RC beam by rebar corrosion in each section of beam. Therefore this study examined the relation between degree of rebar corrosion and load bearing capacity of RC beams by the durability test with the section corroded beams and compared between experiment results and other studies.
