Abstract

Axial load tests and cyclic load tests for FRP reinforced rectangular CFT columns were carried out The main parameters were width-thickness ratio of a steel tubeand FRP layer numbers for the axial load tests and were concrete strength and FRP layer numbers for cyclic load tests. The maximum strength and ductility capacity were compared between the current CFT columns and the FRP reinforced CFT columns. Finally, the axial design formulas were presented for the FRP reinforced CFT columns.

본 연구에서는 FRP 보강된 각형 CFT기둥의 중심축하중 실험과 이력거동실험을 수행하였다. 실험변수는 중심축하중 실험에서는 폭-두께비, FRP보강겹수이며, 이력실험에서는 콘크리트 강도와 FRP 보강겹수이다. 실험체의 내력과 연성능력을 정리하였고, FRP로 보강된 각형 CFT기둥의 압축내력 설계식을 제안한다.
