摘要
以盐源金河雅砻江大桥 170m跨径的钢管砼劲性骨架在施工过程中的结构计算为研究对象 ,考虑几何非线性 ,采用平壳 -桁 -梁组合结构的空间有限元分析模型 ,探讨了拱肋砼浇筑过程对结构内力。
Considering geometric nonlinearation of the bridge during construction,structural behavior of the concrete filled steel tube stiff skeleton of Jinhe bridge over Yalong River in Yanyuan with a span of 170m is analyzed,with the aid of the mixed structure model with the shell,truss and beam member using finite element method.The internal force,deformation and stability during construction of the arch rib of the bridge are also discussed in detail.
