摘要
以某大跨度钢管混凝土拱桥为分析对象,应用大型通用软件ANSYS探讨了结构几何非线性对该桥的自振特性及静力受力性能的影响.结果表明:结构几何非线性对该桥的动力性能及结构的内力影响较小,但对结构的变形有一定的影响,在工程设计中应予考虑.
Considering some long span concrete filled steel tube arch bridge,the effect of structural geometric nonlinearity on natural vibration behavior and the properties of static is analyzed by using general finite element software ANSYS. The results show that structural geometric nonlinearity has little influence on the properties of dynamic and the structural internal force,but it has much influence on the structural deformation, so it can be considered in the design.
