Behavior of Square Concrete Columns Confined by FRP Composites

FRP 합성재료에 의하여 구속된 정사각형 콘크리트 기둥의 거동

Three series of 36 short square columns confined by wraps, full shells and partial shells were tested by varying the thickness of GFRP laminates. An assessment of the effectiveness of the existing model on confinement of concrete columns with FRP was made. Test results indicated moderate increases in strength, but significantly enhanced deformability compared with those in unconfined concrete, particularly the warp and full shell confinement.
