摘　　要：应用双重非线性有限元分析方法对钢管混凝土(单圆管)肋拱受力全过程的非线性性能与极限承载力进行了参数分析。分析的参数有矢跨比、长细比、含钢率以及加载方式。分析结果可供提出极限承载力实用算法和工程应用参考。With the dual non-linearity finite element program, the nonlinear behaviors and ultimate load-carrying capacitys of the Concrete Filled Steel (single)Tubular (CFST) rib arches are analyzed for the whole stressing process. The analyzed parameters include the rise to span ratios, slenderness ratios, steel ratios and loading conditions. The results can be referred to in putting forward an practical algorithm for the ultimate load-carrying capacity of the CFST arches, and can be useful for practical engineering.
