The seismic analysis and performance of steel frame with additional low-yield-point steel dampers

This paper describes the seismic performance of a steel frame with additional LYP dampers. dampers provides passive energy dissipation device in structure, it also reduces lateral forces efficient way which is produced by wave. The structures needed design especially countries where activities occur. analysis accomplished FEM and software called SAP2000. only analyzed using numerical simulation. two frames, first story without while second has mechanism was help nonlinear time history technique results for inter-story drift, base shear, displacement top stress obtained. taken out three different earthquake waves according to Chinese code buildings; were divided into levels China include frequent, moderate rare level. on earthquakes China. modal obtain frequency period frames. frames examined under load combination described buildings internal members axial force, shear force bending moment. combinations are used get We notice that addition increases resistance as we can observe reduction story, drift angle frame. be able behavior pushover analysis.
