An Experimental Study of Reinforced Concrete Columns Strengthened by Carbon Fiber Sheet

탄소섬유시트를 이용하여 보강된 철근콘크리트 기둥의 구조성능에 관한 실험연구

Every structure has the expected life span of its own and it has to be rebuilt. New buildings were preferred and put value a quantitative spread of apartment houses because of the rapid growth of national economy. Therefore, the apartment houses were not taken into consideration about maintenances. Carbon fiber sheet is widely used to strengthen old structural members but it is very rarely applied to a construction field for apartment houses. The purpose of this study is to develop effective strengthening methods for reinforced concrete columns using carbon fiber sheets. Eight reinforced concrete column specimens confined by carbon fiber sheet of uniaxial direction were tested using 10,000kN universal testing machine (UTM).
