摘　　要：该文利用非线性时程分析方法对安庆长江大桥粘滞阻尼器的阻尼系数和速度指数进行了详细的参数分析,讨论了阻尼器各参数对结构地震响应的影响。结果表明:粘滞阻尼器能显著地减小桥梁结构的地震响应。最后,对阻尼器的参数提出了建议以供参考。This paper makes a detailed analysis to the damping coefficient and speed index of viscous damper for Anqing Yangtze River Bridge by the non-linear time history analysis method,and discusses the influences of different parameters of damper on seismic response of structures.The results demonstrate that the viscous damper can obviously reduce the seismic response of bridge structures.Finally,this paper gives a proposal for the parameters of viscous damper for reference.
