摘要
贵州坝陵河大桥为主跨1088 m的钢桁加劲梁悬索桥。利用ANSYS建立钢桁梁耳板节点的空间模型,进行弹塑性分析。通过对耳板节点进行足尺模型静力试验,得到静力荷载作用下钢桁梁耳板节点上各测点应力。结合有限元分析和模型试验结果,分析钢桁加劲悬索桥耳板节点的应力分布及传力机理,对耳板节点的承载能力做出评价。
Baling River Bridge in Guizhou is a stiffening steel truss gi with a main span 1 088 m. By using the ANSYS, the 3-dimensional finite ear-plate joint of the stiffening steel truss girder was created and the ela rder suspension bridge element model for the stoplastic analysis was performed. The static test for the full-scale model of the joint was made as well and the stress of various testing points on the joint under static load was obtained. In accordance with the results of the finite element analysis and the model test, the stress distribution and stress transferring mechanism of the joint were analyzed and the bearing capacity of the joint was consequently evaluated.
