- Abstract
- 본 연구에서는 수직 하중을 받는 철근-콘크리트 기둥 단면의 구조적 거동을 규명하기 위해 철근의 부식팽창과 콘크리트 계면의 공극을 고려하여 유한요소 해석을 통해 철근 부식량의 증가와 함께 RC기둥의 횡방향 저항력은 증가후 감소하는 것을 ㅗ학인했다 또한 철근 부식에 대한 RC구조물의 구조적 성능 및 내구성 측면에서 철근을 둘러싼 콘크리트 계면의 공극은 유리한 역할임을 확인했다
In this study, a development of the rust formation was modelled to quantify the structural impact at the steel-concrete interface in terms of the risk of cracking, which can substantially be used for a parameter to the serviceability of concrete structures subjected to a corrosive environment. As a result, it was found that there was no risk of cracking and structural limit until the rust was formed within the interfacial gap.
