The relationship between true stress and true strain of structural steel was simply modeled considering the Bauschinger effect. This hysteresis model is composed of skeleton curve based on the material test result, Bauschinger part modeled as a function of the cumulative strain in the skeleton curve and elasticity unloading part. The analytical result of the beam which applied this hysteresis model was compared with experimental result. The analytical result and the experimental result showed the good correspondence in not only load deformation relationship but also deformation of skeleton curve as an index to the plastic deformation capacity of member, moment-curvature relationship and hysteresis of strain. Though the hysteresis model is simple, it is enough effective in order to analyze the behavior of steel member in the plastic range.
