[摘要]  本文针对某大跨转换结构高层建筑，在大跨转换位置采用非线性粘滞阻尼器耗能装置对结构进行减震控制研究。基于通用有限元弹塑性时程分析，通过改变粘滞阻尼器速度指数得到无控和有控，以及有控中不同粘滞阻尼器速度指数的结构层间位移角，阻尼器滞回曲线的对比结果。结果表明：在结构和阻尼器布置一样情况下，粘滞阻尼器速度指数最小的工况减震效果最明显。

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.
