Bond Behabior Between Deformed Aramid Fiber-Reinforced Plastic Reinforcement and Concrete

Abstract eng:
Recent years, Fiber-Reinforced Plastic (FRP) reinforcement has been utilized for concrete structures expecting its high durability to corrosion and insulation property. In this study, pullout loading test and tensile loading test is performed to investigate the bond behavior between AFRP reinforcement and concrete. The test parameters are cross sectional size of concrete block, elastic modulus and nominal diameter of AFRP reinforcement. The test results of pullout loading test show that bond behavior is influenced by surface figure of AFRP reinforcement. The results of tensile loading test show that crack width depends on elastic modulus. Tension stiffening behavior of AFRP reinforcement is almost same in spite of the type of AFRP reinforcement.
