摘要
由于大跨径钢桁梁桥的施工过程较为复杂,尤其是采用悬臂施工法且中跨采用悬臂合龙时,对成桥后的个别杆件受力状态影响较大,因此采用中跨无应力合龙符合钢桁梁的受力要求。本文通过有限元软件对钢桁梁桥采用无应力合龙方式进行位移、应力和稳定性的分析。
The construction process of long-span steel trussis relatively complexed. The method of cantilever construction has great influence on the stress state of the individual bars andnon-stress consolidation meets stress requirements. In this paper,the analysis of displacement,stress and stability of steel truss bridge is carried out by using finite element software.
