Abstract: It is studied that nonlinear viscous dampers were used in the large span transfer position in a high-rise building to reduce the structural responses under earthquake. By way of elastic-plastic time-history analysis based on general finite element software, we can analysis structural story drift and damper’ hysteretic performance of the uncontrolled structure and controlled structure, as well as controlled structure of the different speed index. In the case with the same structure and arrangement of dampers, the analysis result indicates that using viscous dampers with the minimum speed index can effectively improve the structural seismic performance.

Keywords: large span transfer structure；viscous damper；Elastic-plastic time-history analysis；speed index
