Finite Element Simulation Analysis of Central Pull-out Experiment of Steel Bar and Recycled Concrete

In order to study the bond performance of steel bars and recycled concrete, the ultimate bond stress distribution between recycled concrete and steel bars is analyzed through central pull-out test, and the influence of steel bars grooving on actual stress distribution is considered. Therefore, in this paper uses the finite element software ABAQUS is used to simulate the central pull-out test of steel bars and recycled concrete, and to discuss the bond force distribution between steel bars and concrete. The results show that the finite element simulation analysis results of the central pull-out experiment of steel bars and recycled concrete are in good agreement with the experimental results, which verifies the accuracy of the finite element model.
