Abstract
본 논문에서는 염해에 의하여 열화된 철근콘크리트 구조물의 보수 LCC평가 방법에 대하여 연구를 수행하였다. 또한, 철근콘크리트 구조물의 목표내용년수 동안에 건설초기 공법과 염해보수 공법을 포함한 보수 LCC를 평가하기 위하여 콘크리트내로의 염소이온 침투를 FEM 해석으로 실시함으로써 보수횟수를 결정하였다. 그 결과. 염해 보수 횟수는 보수재의 종류 및 보수방법을 고려한 FEM해석을 통하여 철근위치에서의 염소이온 농도와 철근부식 임계염소이온 농도를 비교함으로써 산정할 수 있었으며, 염해 보수 횟수를 이용하여 목표내용년수 동안의 보수 LCC를 산정하는 것이 가능하였다. In this paper the method for repair LCC evaluation of reinforced concrete structures deteriorated by chloride attack was constructed. Also, the FEM analysis for chloride ion penetration into concrete was conducted to evaluate the repair LCC which was decided by the number of repair times including early stages of construction and repair construction during the service life of structures. As a result, the number of repair times is obtained from the comparing the concentration of the chloride ion in a rebar position. and the critical chloride ion concentration of rebar corrosion through the FBM analysis considering the kind of repair materials and methods. Also, the repair LCC could be calculated by the number of repair times during the service life of structures.
