Simple Experimental Model for Bond Stress and Slip Between HPFRCC and FRP Strip Used as a Permanent Form

Authors : Seung-Woon Yoo

Abstract: Using a GFRP (Glass Fiber Reinforced Polymer) strip was used as a tensile bar and concrete form markedly reduces the construction period and construction costs. A local bond stress and slip model that is critical in the analysis and design of the concrete combined structures was suggested. Two types of FRP planks were utilized as permanent form and tensile reinforcement to perform a comparison test about the bond stress between the FRP and concrete. GF12 of RFCON was 2.00~2.50 MPa and GF22 was 2.80~5.10 MPa. For the simple model this study suggests in case of RFCON, the maximum mean local bond stress is 3.10 MPa, the initial gradient is 55.49 MPa/mm and the total slip is 0.28 mm. In this study, an experiment of flexural bonding failure were performed and results were analyzed to study the bonding and slip behavior between FRP strip and concrete. It was proposed a simple experimental model that can be easily applied to the composite concrete structures.
