반복하중을 받는 철근콘크리트 보-기둥 접합부의 보강에 따른 구조성능 평가
Evaluation of Structural Performance of Reinforced Concrete Beam-Column Joints Strengthened with Various Retrofitting Under Cyclic Loadings
In this study, experimental research was carried out to evaluate the structural performance of reinforced concrete beam-column joint using steel plate, carbon fiber, and aramid fiber materials in existing reinforced concrete building. Test result shows that Retrofitting specimen (LBCJ-SP45, LBCJ-CS1, LBCJ-AF1) designed by the improvement of structural performance and ductility using various materials(steel plate, carbon fiber sheet, and aramid fiber sheet) could attained more load-carrying capacity and stable hysteretic behavior. The load-carrying capacity of each specimen was increased 25.8~49.5% in comparison to standard specimen.
