摘要
介绍了大跨度钢管混凝土拱桥空间稳定分析方法。基于有限元理论,考虑结构的几何非线性和材料非线性,建立了某中承式钢管混凝土拱桥的计算模型,运用ANSYS软件对该桥施工过程和运营阶段的稳定性进行了模拟计算,其结果为大桥的设计和施工提供了理论依据。
A method for special stability analysis of a long span concrete filled steel tubular (CFST) arch bridge was developed based on FEM with considerations of both geometrical non()linearity and material nonlinearity. Using the method, analyses were conducted on the stability during construction and service of the bridge with results providing the basis for the design and construction.
