Therefore , all the ready - made bridges must be urgently analyzed to assess their anti - seismic capacity . the bridges that ca n ' t meet the requirements of ductility must be strengthened 因此，迫切需要对我国既有桥梁的延性抗震能力进行分析，对不满足延性要求的桥梁进行抗震加固。
According to damage mechanism analysis , finite element models are developed to simulate the dynamic experiments , and the anti - seismic effect of model strengthened with cfrp is studied and contrasted 同时运用有限元程序建模进行了计算，分析了不同试验模型的损伤机理，对比了根据不同损伤机理进行抗震加固的效果。
In connection with the practice of rehabilitation of maju elevated bridge on the 2nd - loop way in beijing , the application of the relevant new technics and new materials in reforming and seismic - strengthening of the existing bridges are briefly introduced 结合北京市公路二环马驹桥立交桥改建的工程实践，简要介绍有关新技术新材料在桥梁改建和抗震加固方面的应用。
A lot of earthquake damages at home and abroad have showed the vulnerability of existing building structures , which fully proved the importance of evaluating the earthquake resisting behavior of existing building structures 如何评定这些已建建筑结构的抗震性能，并据此进行合理的抗震加固，对最大限度地降低地震震害损失以及保护人民生命财产安全，都具有重要意义。
These studies will take important part in intending structure inspection , seismic appraiser ; seismic strengthening of historic timber structure buildings , and will provide very useful suggestions to modem building construction 并提出了针对具体情况对古建筑文物进行维护、修复、加固的方法。这些研究对现存木结构古建筑的结构u 、抗震鉴定、抗震加固具有实际意义。
However , as a new kind of antiseismic structural materials adjusting to the high development nowadays , although has been widely used in bridge construct and decoration building , ect , expansion web is still lack of studying on its antiseismic behavior 扩张网作为一种新型建筑材料，已经广泛地应用于桥梁建设和房屋装饰等方面，但对其在结构抗震加固方面的研究却很少。
And the system can be expressed with damage matrixes , which forms a clear and intact dendriform damage evaluated method , offering a practical basis of quantization for seismic design , seismic reinforcement and repair of buildings after earthquakes 该体系可用矩阵形式表示,总体上形成了层次分明、分支完整的树状评估体系,可以为抗震设计、抗震加固和震后维修提供明确实用的量化依据。
Abstract : the article analyzed the key link to the choosing structure forms , dealing with foundation , resisting earthquake consolidation , etc . on desings of the additional storeys and renovation of old brick buildings , this paper provided some ways and theroretic basis 文摘:就旧砖房增层改造设计中的结构形式选择、基础处理、抗震加固等关键环节进行了分析，为做好砖房增层改造设计工作提供了方法、理论依据
Compared with other dampers , vdw has its specific advantages such as the full utilization of space , the provision of larger damping force , the convenience of installation , and the low cost of maintenance and so on . vdw not only can be applied in the earthquake - reduction design of new buildings , but also be used in the aseismatic retrofitting of existing buildings 与其它阻尼器相比，粘滞阻尼墙可充分利用墙体所提供的空间，产生足够大的阻尼力；既适合新建工程的减振设计，又能用于现有结构的抗震加固，且安装方便、维护成本低，是目前较为理想的阻尼消能元件。
In this paper , the researching and developing situation at home and abroad on cement mortar reinforced with steel mesh used in aseismic reinforcement are firstly reviewed . based on experiments on three brick walls unstrengthened and strengthened , the forces , deformations and damaged patterns of walls bearing vertical and cyclic horizontal loads of multi - storey brick buildings are discussed 本文首先回顾了国内外关于钢筋网水泥砂浆抗震加固的研究和发展现状。通过三片砖墙加固前后的试验，探讨了多层砖房墙体在循环水平荷载和垂直荷载共同作用下受力、变形及破坏形态。
