The semi-rigid connection joint in steel frame could be characterized by a meso-damage model which was composed of a set of brittle linear-elastic flexural springs of equal stiffness joined in parallel.And the nonlinear performance of the moment-rotation curve of the joint was analyzed. Based on the equilibrium equation and damage theory,a damage constitutive model of steel frame joint subjected to monotonic moment was deduced. The coefficients used in the model could be determined by initial flexural stiffness and ultimate moment. It was found that theoretical curve had a good agreement with experiments.
