【摘要】 本文通过对阜成门立交桥抗震加固设计及总结,展示了粘滞阻尼器在市政桥梁加固时的设计方法,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受力需求的增加。更多还原

【Abstract】 Through the seismic strengthening schemes summarized of municipal bridges,such as Fu Cheng Men bridge, An Ding Men bridge, De Sheng Men bridge etc., this article shows the design method of viscous dampers in the municipal bridge strengthening, at the same time, this paper reveals the advantages of this reinforcement measures in engineering cost, traffic affects and implementation by comparing with conventional strengthening technology. The research results show that: in three or four span simply supported, 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 impact, which is suitable for wide application. But in seismic reinforcement design, displacement goal should be definite, and should also pay attention to local stress increased demand of the connection member after strengthening.更多还原
