There are many factors which influence the creep of concrete-filled steel tubular arch bridge, while the theory researches lag behind practice. Based on the computing formula of creep coefficient in code, the creep function is formulated. The computing method of creep in structure analysis is deduced, using the integral concept to stress and time. Combined with the calculation of Meixi River Bridge, it is pointed out that creep affects the displacement of CFST arch bridge prominently, which will lead to redistribution of internal force, and it should be recognized by engineering circle.
