This paper proposes the design of a scheme for a long span simple-supported arch bridge and its bracket. The design scheme is based on engineering examples and an actual engineering situation. In order to understand the design of the bracket of the long span simple-supported arch bridge, the feasibility of this design applied to construction is determined. MIDAS-Civil inite element software is used to establish the calculation model of a 144 m simply supported arch bridge bracket. After checking the stress and de lection of the bracket, the bracket system meets the strength and stiffness requirements of the standard design. The design scheme of long-span simple-supported arch bridge and its bracket proposed in this paper can provide references for similar projects.
