Abstract

In this study, The purpose of this study is to experimentally investigate the shear behavior of reinforced flat plate embedded with GFRP(glass fiber reinforced polymer) plate with openings. The GFRP shear reinforcement is manufactured into a plate shape with several openings to ensure perfect integration with concrete. The test was performed on 7 specimens. the parameters include the type of reinforcement and amount of the shear reinforcement., From the test, we analysed the crack, failure mode, Strain, load-displacement graph. a calculation of the shear strength of reinforced flat plate with GFRP plate based on the ACI 318-11 was compared with the test results. The results of the experiment indicate that GFRP plate is successfully applied as a shear reinforcement in the flat plate under punching shear.

본 논문에서는 새로운 형상의 GFRP 판으로 전단보강된 플랫 플레이트의 전단거동에 관하여 실험적으로 연구하였다. GFRP 판은 개구부가 있는 판의 형태로서 콘크리트와의 일체화 거동을 위하여 콘크리트에 매립하여 사용한다. 총 7개의 시험체에 대한 뚫림 전단실험을 수행하였고, 실험 변수로는 전단보강재의 종류와 전단보강량을 선택하였다. 실험결과를 시험체의 균열 및 파괴양상, 변형률, 하중변위곡선으로 분석하였다. 또한 GFRP 판으로 전단 보강된 플랫 플레이트의 ACI 318-11 기준식에 의한 계산값과 실험에 의한 결과값을 비교하였다. 실험 결과 GFRP 판이 플랫 플레이트의 전단보강재로써 뚫림 전단에 효과적으로 적용함을 확인하였다.
