탄소섬유 보강판 전용 정착장치를 이용한 외부 프리스트레싱 보강공법 사례연구

Case study on the external prestressing method strengthened carbon fiber reinforced plates.

In recent years, FRP plates have been studied for flexural reinforcement of RC structures due to easy installation and good Quality control. This study presents experimental field test results for the effectiveness of flexural reinforcement of the RC slab using external prestressing with thin CFRP strips made by the pultrusion process. It was demonstrated that flexural strength was considerably increased with relatively easy installation when compared to the other methods used for the composite reinforcement.
