Concrete-filled steel tube tied arch bridge is widely used in all kinds of bridge engineering,which has the ad-vantages of high stiffness,strong crossing ability and beautiful shape.In the traditional support design,after the pres-tressed tension,the tie beam and the support can jointly bear the imposed load,which includes the self-weight of arch rib support and the self-gravity of concrete-filled steel tube.Midas/Civil software is used to establish three-dimensional finite element models for disk-buckle bracket arch and bracket beam-column arch.The mechanical characteristics and deforma-tion trends of bracket beam-column arch and bracket beam-column arch under different construction loads are studied.The load distribution law of the support in the late construction condition is obtained,and the relevant research conclusions can provide reference for practical bridge engineering.
