摘要
在采用空间有限元模型对南宁大桥动力特性分析的基础上,采用非线性动力时程分析方法,对南宁大桥粘滞阻尼器参数(阻尼常数C、阻尼指数ξ)进行敏感性分析,得出粘滞阻尼器参数对南宁大桥地震响应的影响规律。
Based on the analysis of the dynamic behavior of Nanning Bridge by means of spatial finite element models, the nonlinear dynamic time history method is used to conduct the sensitivity analysis of the parameters of viscous dampers (damping constant C and damping exponent ξ) of the Bridge and the laws of influence of the parameters on the seismic response thereof have been obtained.
