Under cyclic loading, the structural performance of reinforced concrete (RC) beam-column connections is significantly affected by the bond-slip of beam re-bars. In the present study, a bond-slip model was developed to evaluate bond-slip of beam re-bars in beam-column joints. The prediction of the proposed model agreed well with the bond strength degradation and bond-slip in the beam-column joints.
