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、变形及稳定性的影响
关键词: 拱桥, 钢管砼, 施工, 结构稳定性, 非线性分析
Abstract: 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.
Key words: arch bridge, concrete-filled steel tube, construction, structural stability, nonlinear analysis
