Based on the test and numerical simulation research,the design method of the resilient prestressed steel frame structure with intermediate column dampers was proposed with the detailed design process. Thereafter,according to this design method and design process,a 10-story resilient prestressed steel frame structure with intermediate column dampers was designed. Parameters of the structure under the frequent and fortification earthquakes with 8 th degree of earthquake fortification intensity were analyzed, including the shear force of base, the interlayer displacement angle, the post-earthquake residual displacement angle of each layer and the slipping value of intermediate column dampers. Results show that the applicability of the design method is verified because prestressed steel frame structure with intermediate column dampers after performance-based design meet the design requirements of no gap opening and no damages under frequent earthquake,meanwhile the gap opening for energy dissipation and no damage to main structures under the fortification earthquake, and the structure has strong lateral stiffness, good energy dissipating capacity and evident automatic resilient advantage.
