1.The authors describe the modelling of a railway steel truss bridge with long-span in order to analyse the detailed distribution of stress for members and nodal plates in main truss, the detailed deformation and stress distribution due to frame effect on transversal bracing plane in truss bridge, and the detailed distribution of stress in important parts of the steel plate girder bridge with initially transversal deformation by using SSEB in this article.
2.4. Taking a bridge for example, the 3D finite model composed of shell element is used to analyze the stress disturbing of main loaded members of steel anchorage and to summarize the force transmission route.
