Abstract
This article presents the effect of the thickness, the modulus of elasticity and the strength of the carbon fibre-reinforced-polymer (CFRP) plate on the CFRP-metal couples for the structural rehabilitation and retrofitting applications. This article illustrates the development and assessment of a novel prestressing anchor to grip the commercially available 50â¯mmâ¯Ãâ¯1.4â¯mm CFRP plates. This is a high-modulus CFRP plate with a modulus of elasticity of 210,000â¯MPa and an ultimate tensile strength of 2900â¯MPa. The new anchor was made of 22-gauge (0.71â¯mm thick) annealed copper and heat-treated H13 steel. An ABAQUS-based finite element advanced simulation model of the bolted anchor was developed to analyze, optimize and design the new anchor. A detailed manufacturability study was conducted. An experimental investigation was carried out to authenticate the numerical simulation results. The average failure load of this new anchor was 231â¯Â±â¯6â¯kN, which was more than 100% of the guaranteed ultimate tensile strength of the high-modulus CFRP plate (203â¯kN). The failure mode was the sudden tensile failure of the CFRP plate outside of the anchor.
