FRP로 횡구속(橫拘束)된 철근(鐵筋)콘크리트 기둥의 철근비(鐵筋比) 변화에 따른 압축거동(壓軸擧動)에 관한 실험적(實驗的) 연구(硏究)

다국어 초록 (Multilingual Abstract)

The purpose of this experimental study examine the structural performance of RC columns reinforced with CFS and FGRTP, a kind of high strength fiber. This experimental study have two parameters of the way confined (carbon fiber sheets, fiber glass reinforced thin plate) and steel ratio(1.57%, 3.08%, 5.09%,).
The CFS can be made very thin, resulting in flexibility sufficient for them to be wrapped around circular as well as rectangular columns.
As well as ductility of column strengthened with sheet also increase from the confinement effect by FGRTP. While non-FGRTP later confinement specimens appeared sudden failure after shell concrete was tom off, specimens confined laterally with FGRTP were showed that their failure, flexibility and strength enhancement.
The objective of experimental study is to evaluate the strengthening effects of concrete compression confined with carbon fiber sheets and FGRTP(Fiber Glass Reinforced Thin Plate).
