Experiments on concrete filled steel tubular (CFST) model arches with new-type dumbbell-shaped section have been carried out, concentrated loading at crown and L/4 section respectively. Applied with large general program ANSYS, a finite element calculation model was set up for the model arch, by means of this model the main parameters including arch axis coefficient, ratio of rise to span, slenderness ratio, and steel ratio are analyzed. Based on the discussion of influence of parameter variation on nonlinear characteristics and ultimate load-carrying capacity of model arch, the theoretical basis is established for the development of this structure and the conclusion can be taken as reference in practice use and further research work.
