| 摘 要： | 采用线弹性、几何非线性、双重非线性三种方法,对大跨度钢管混凝土系杆拱桥极限承载力进行了分析,并讨论套箍效应和布载方式对极限承载力的影响。计算结果表明,对结构极限承载力分析时应考虑双重非线性和套箍效应,布载方式对极限承载力有很大影响。

| Abstract: | By adopting the linear elastic,the geometric nonlinearity and the double nonlinear,the study undertakes the analysis of the ultimate bearing capacity of large-span steel pipe concrete tied arch bridges,discusses the influence of the confined effect and the ways of the loading arrangement on the ultimate bearing capacity,and proves by the calculation results that the double nonlinear and the confined effect should be considered in the analysis of the structural ultimate bearing capacity and the ways of the loading arrangement has the impact on the ultimate bearing capacity. |
