Shear strengthening of concrete beams with embedded frp bars

[摘要] With increasing numbers of strength-deficient concrete infrastructure assets, strengthening and repair of concrete structures is becoming an issue of international importance. This thesis investigates the behaviour of shear-strengthened reinforced concrete (RC) deep beams, which can be found in many concrete infrastructure assets including bridges and high-rise buildings. The thesis examines the bond performance of the deep embedment (DE) technique, also known as the embedded through-section technique (ETS), which utilises fibre reinforced polymers (FRP) bars embedded into concrete using an epoxy adhesive. The bond-slip experimental results were used to develop a nonlinear finite element (NLFE) model for DE-strengthened RC deep beams. After validation, the NLFE model was used to carry out a parametric study, the results of which were used to formulate design models for DE-strengthened RC deep beams.
