Abstract:: In order to simplify the design process of buckling restrained steel plate shear wall-steel frame, a macro element model called two-spring model was proposed, and the mechanical properties of buckling restrained steel plate shear wall-steel frame were simulated. Based on the theoretical analysis and experimental data, the skeleton curve and hysteretic rule of the shear spring, along with the skeleton curve of the bending spring, were obtained. The above parameter values were compared with the experimental results. Furthermore, the numerical results which were obtained by the macro element model method were compared with those obtained by refined finite element method. The results show that the parameter values obtained by theoretical deduction are in good agreement with the experimental data. The results of the numerical models built by two different methods are basically consistent. The parameter values of the macro element model are accurate, and the real mechanical properties of the structure can be accurately reflected.
