A spatial finite element method (FEM) model was established to analysis the structural stability of an actual concrete filled steel tubular (CFST) basket handle arch bridge. Various factors affecting stability analysis were fully considered. Moreover, the influence of the rib inclination angle on stability was investigated in detail. Dual nonlinear stability analysis under lane loading in bridge completion state was carried out. The results show that the arch rib is mostly at risk of out-of-plane instability, and a moderate introversion is acceptable. On the other hand, the ultimate bearing capacity meets the demand, and the arrangement of load combination has great effect on ultimate bearing capacity.
