摘要
四渡河大桥主桥为单跨900 m双铰钢桁梁悬索桥。主桥加劲钢桁梁的节点板处构造及受力均较复杂,采用通用有限元软件对代表性的节点板处局部应力进行空间分析,为设计提供了参考。
The main bridge of the Sidu River Bridge is a double-articulation steel truss girder suspension bridge with a single span 900 m. At the gusset plates of the stiffening steel truss girder of the bridge, both the structural formation and stress conditions are complicated. In this paper, the universal finite element software is used to conduct a spatial analysis of the local stress at the typical gusset plates to provide reference for the design.
