Abstract

본 논문에서는 유공형 형상의 GFRP 판으로 전단 보강된 플랫 플레이트의 전단거동을 실험을 통해 평가하였다. GFRP 판은 개구부가 있는 판의 형태로서 콘크리트와의 일체화 거동을 위하여 콘크리트에 매립하여 시공하였다. 실험 변수로는 기둥면과 첫 번째 GFRP 판의 세로 스트립 사이의 간격, GFRP 판의 세로 스트립의 개수를 선정하였다. GFRP 판의 세로 스트립의 개수가 증가할수록 전단강도도 증가하는 결과를 보여주었다. 실험결과를 바탕으로 GFRP 판으로 보강된 플랫 플레이트의 전단강도가 ACI 318, BS 8110, EUROCODE 2, KCI에서 제시하고 있는 전단강도와 비교하여 가장 합리적인 규준을 평가하였다.

In this study, shear test performed to investigate the shear behavior of flat plate that reinforced by embedded GFRP(glass fiber reinforced polymer) plate with openings. Shape of the GFRP shear reinforcement is a plate with several openings to ensure perfect integration with concrete. The test parameters include the distance between the column face and the first line of GFRP plate and number of GFRP plate vertical strip. The result of test showed that when number of GFRP plate vertical strip was increased, shear strength improved. The shear strength for flat plate reinforced GFRP plate in various codes including ACI 318, BS 8110, EUROCODE 2, and KCI were compared to provide more rational approach for reinforced concrete flat plates with GFRP plate.
