RCS construction method is to take an advantage by applying reinforced concrete column and steel beam. RCS construction method has a complex structural analysis, compared with single structural system, due to interaction of different material, behavior of load distribution, diversity of joint detail and failure behavior. Therefore, this study aims to describe behavior of RCS joint as a simplified analysis model. The first, for understand behavior of RCS joint through test literatures related to RCS from the inside and outside of country and presented an analysis model, which to reflect each characteristic. So first of all, the researcher divided RCS specimen into four groups, according to its form and stress distribution element. The 'C' group, which is a flexural failure model, was explained properly using a factor in not order to generate stiffness reduction, strength reduction and pinching with polygonal model. The 'A', 'B' and 'D' groups, which are origin oriented models, were explained properly using smooth model and they had little bigger values in stiffness and strength reduction than general RC joint and a factor of pinching was explained through a combination among slip length, slip sharpness and moment level of slip in each group.
