摘要: 以广西永和大桥为实例建立计算模型,利用大型空间分析软件MSC.Nastran对永和大桥在施工阶段的线性稳 定性和非线性稳定性进行了对比和分析,分析表明应该采用非线性分析来评价大跨钢管砼拱桥的稳定性才有实际 意义.
关键词: 钢管拱, 转体施工, 稳定性
Abstract: The model of Yonghe Bridge was built and the comparison between linear analysis an d non-·linear analysis was con-· ducted by the software MSC Nastran.The results show that it is practical to evaluate the stability of the concrete-filled steel tube arch bridge with non-linear analysis.
Key words: concrete-filled steel tube arch, rotation construction, stability
