摘要

摘要: 该文通过对阜成门立交桥抗震加固设计的总结,展示了粘滞阻尼器在市政桥梁加固时的设计思路,同时与常规加固技术进行比较,揭示了该加固措施在工程造价、交通影响、可实施性等方面的优势。论文研究成果表明：在三、四跨简支、连续梁桥,采用附加粘滞阻尼器作为加固方案,不仅成效显著,而且具有造价低、可实施性强、交通影响小等优势,适于推广应用。但在减震加固设计时应具有明确的位移目标、同时应注意加固后连接构件局部地震需求的增加。结论

Abstract: Through the summary of seismic strengthening design of Fuchengmen bridges, the design method of Fluid viscous damper (FVD) when seismic strengthening were shown in this paper. By comparing with the conventinal strengthing method, the advantages of using FVD in engineering cost, traffic affects and implementation are discussed herein. The research results show that: for three or four span simply-supported bridges, or continuous girder bridge, the reinforcement scheme of adding viscous dampers, not only is effective, but also has low cost, strong implementation and small traffic impacts, which is suitable for widely application. But when doing seismic strengthing design, displacement goal should be defined clearly and the increase of seismic demanding in the connection members after strengthening should be paid more attention to.
