Abstract Based on published bond-slip model of reinforced concrete member under low frequency reversed loading, a new one with corroded reinforcement was established. The new model corrected some relative parameters theoretically in the mesoscale, such as cyclic bond-slip envelope, adhesive stress factor, frictional stress factor, reversed stress, residual stress and corresponding slip value. Comparing with the existing test results, it shows that the new model is viable in practice. The obtained results are very significant for evaluation of aseismatic behavior of corroded reinforcement elements.
