Abstract Research purposes: Combined with the characteristics of concrete—filled steel tube arch bridge，the introduction is given in this paper to the design of the concrete—-filled steel tube arch bridge of the Songhua River Grand Bridge and the three—dimensional simulation analysis and comparison are made for the static，buckling，self—vibration characteristics and reinforcement of crossbeam of the bridge by using Grillage model and the single beam model with the professional finite element software MIDAS．

Research conclusions:From the research it is concluded the transverse layout of support is of great significance to choosing the tonnage of support，and the numerical values obtained from the grillage model is very close to that obtained from the single beam model under the effects of various working condition except under the effect of the secondary contraction．The stiffness，rotation angle，creep on the deflection obtained from the grillage model are almost the same as those obtained from the single beam model．It verifies the rationality of the design and provides the favorable basis for the design．

Key words： concrete—filled steel tube arch bridge single beam model grillage model
