The yield surface of section axial force and bending moment (AFBM) is formulated by section assemblage concept. Based on flexibility method , a novel planar beam- column element is proposed using yield surface of section AFBM. Dynamic elastoplastic analysis is carried out on a planar steel frame. The results show that the accuracy of proposed model is close to fiber model, and hence it can be used for dynamic elastoplastic analysis of frame structures.
