Ductility Improveent Methods for Cncrete Beams Prestressed with FRP (Fiber Reinforced Plastic) Tendons

FRP 긴장재를 이용한 프리스트레스트 콘크리트보의 연성개선방법

Despite many advantages of FRP materials, such as corrosion resistance, their linear elastic behavior up to rupture is likely to result in a lack of ductility. This paper discusses ductility improvement methods for prestressed concrete beams using FRP tendons. The methods were evaluated thorough extensive analytical and experimental investigations. The methods include optimization of sectional ductility through proper reinforcement, concrete confinement, concrete reinforcement with fibers, and prestressing with unbonded tendons.
