Abstract：In view of the proposed resilient prestressed prefabricated steel frame structural system, the modal analysis and the dynamic elasto-plastic analysis of the integral structure are investigated by ABAQUS, as well as the comparative analysis of base-shear force, story drift, residual story drift, equivalent plastic strain and energy dissipation with rigid steel frame and resilient prestressed steel frame under different seismic levels. The research indicates that, the resilient prestressed prefabricated steel frame still keepselastic under 8 degree frequent and design earthquake. The energy dissipation of the structure depends on the damping and friction dissipation damper under the 8 degree rare earthquake, minor portion for inelasticity relatively, which reduces the main structure plastic development and damage. Resilient prestressed prefabricated steel frame has the better seismic behavior than resilient prestressed steel frame.
