摘要
钢桁桥造型美观,材料用量较省,结构承载能力高,刚度大,随着我国经济的发展,交通量的不断增大,其应用将会越来越多。本文对影响公路钢桁桥稳定性的因素,包括横向风荷载、横梁刚度、平联刚度、桥面板刚度、纵横梁连接方式、横梁与主析连接方式等进行了计算分析,得出了一些有意义的结论,可供施工参考。
Steel truss bridge has been widely used for it＇s advantages of beautiful shape,goodability of taking load,material savad and high stiffness.As the economic development andincreasing traffic of China,the application of steel truss bridge will be more and morewidely This paper haves given consideration in factors that influences the stability of Steel truss bridge such as horizontal windload,beam stiffness,lateral stiffness,the bridge deck stiffness,the connections betweenlongitudinal beam and cross beam,the connections between cross beams and the main truss and so on when calculating and analyzing the overall stability factor in construction process.Physically,it also obtain some beneficial conclusions,which can provide a reference for theconstruction.
