Finite Element Analysis of Bond Slip Constitutive Model of FRP Reinforced Concrete

ABAQUS has strong nonlinear analysis ability, so the numerical analysis of bond slip constitutive relation between FRP bars and concrete has been carried out with ABAQUS. By comparing the results of numerical calculation of different constitutive model, the constitutive relation of plastic reinforcement and concrete is obtained, and the suitable constitutive model is chosen, which provides the basis for the study of the structure selection in future, and it can also provide reliable numerical results for the future real experiments.
