Application of reinforced concrete bond slip connection element under cyclic load

In order to study the influence of bond slip performance of reinforced concrete in the process of numerical analysis, a connecting element is proposed to simulate the bond slip performance between reinforced concrete elements, and the loss of bond strength under cyclic load is realized through motion based exponential damage evolution, This method is successfully used to analyze the existing pull-out tests, and the numerical simulation results are in good agreement with the test results, which proves the applicability and accuracy of this method for studying the bond slip behavior of reinforced concrete under cyclic load.
