A model for predicting the moment rotation relationship of common reinforced concrete joint under certain records of its beam - steel strains is presented. The model takes into account both the in-elastic rotation in the beam in- elastic region and the fixed end rotation at the beam - column interface crack arising from the slip of reinforcement inside the joint. The behavior model of constituent materials follow those had been proposed by Menegotto - Pinto - Kardiyono , Mander - Park - Priestley and Harajli - Mukaddam for reinforcing steel, concrete and steel slip, respectively. Despite lost of some property data, the model gives result in such a good agreement with ex perimental .
