Abstract：This paper puts forward a kind of mega-suspended frame composite support system with damper.The stem department model of this system is simplified as the particle system model ,each layer of the lateral stiffness is deduced by elastic-plastic static method through SAP2000 software and the rationality of the simplification is discussed by SAP2000 software and a self-designed procedure. Based on these,to discuss the elastic-plastic seismic response analysis with three seismic waves through the self-compiling program and it is shown that along with the increase of resist lateral stiffness of the system, deformation energy consumption of the system reduces and the seismic energy consumption by damping increases,but the seismic energy consumption is constituted by deformation energy consumption , while for the mega-suspended braced and prestressed frame with damper, the main structure's horizontal displacement and the differences between main and substructure can be reduced effectively by the viscous damper which can also avoid the collisions and protect the main structure.
