Abstract
In this paper,SAP2000 was used to study seismic vibration control for high-rise steel frame structure with viscous dampers,a lot of analysis and comparison of seismic vibration for steel frame structure was made by using SAP2000 software in finite element method,and finally the reasonable scheme of arrangement of dampers is selected.The result indicated that the viscous damper is suitable to high-rise steel frame structure and its effects of the viscous damper are excellent when the location of viscous dampers was installed in the floor of larger layer displacement or larger displacement angle.
