摘要

为研究粘滞阻尼器在大跨连续梁桥中的抗震性能,结合工程实例建立Midas有限元分析模型,采用非线性动力时程分析方法,比较多种粘滞阻尼器的布置方案,并对粘滞阻尼器进行参数敏感性分析。结果表明,增设粘滞阻尼器能显著改善固定墩在地震力作用下的受力性能,使各墩间的受力更趋均衡,粘滞阻尼器参数C,ξ的变化对结构抗震性能影响较为明显,并针对本工程给出了较为合理的布置方案和阻尼器参数。
Based on practical engineering examples,a Midas FEA model is built to investigate the seismic performance and efficiency of viscous dampers in long-span continuous beam bridge.Thorough non-linear dynamic time-history analysis,the performance of viscous dampers with different layout plan has been studied and compared.The parameter sensitivity has also been studied.The study results show that the viscous dampers have a dramatic impact on the seismic performance of fixed piers,make the piers internal force are more balanced;the parameters C and ξ has most significant impacts on the performance of structure.In addition,the optimal layout and parameters for the engineering examples in this paper have been proposed.
