Initial stress is produced in the construction of concrete filled steel tube (CFST) arch bridge. According to the construction sequence of CFST arch bridge, using the method of the body-space beam element with initial stress in the calculation of the bearing capacity of dumbbell-shaped CFST arch bridge, this paper calculates the bearing capacity of three dumbbell type ribs, analyzes the law of the impacts of the factors of various initial stress coefficients, steel ratios and spans on the bearing capacity of dumbbell-shaped CFST arch bridge. The results show that the initial stress reduces the ultimate bearing capacity of arch rib by nearly 18%.
