Degradation Analysis of Deteriorated Reinforced Concrete Structures due to Cracks and Steel Corrosion

균열 및 철근부식에 의해 열화된 콘크리트 구조물의 성능저하 해석

In this study, an unified algorithm for the degradation analysis which considers the cracks in concrete and steel corrosion is developed and implemented into finite element analysis program. Using the program, degradation analysis on reinforced concrete structures subjected to chloride attacks was carried out with time by considering the cracks and the steel corrosion and cracking due to expansion of corroded reinforcing bars. The analytical procedure proposal in this study can be used quantitative evaluation of degradation and service life prediction.
