The Diagonal-span arch bridge is novel in shape and complicated in force. In order to ensure the safety of the bridge during the tensioning of the hanger, Midas Civil was used to establish a three-dimensional finite element model and four kinds of tensioning scheme are compared. This study analyses the deformation and stress of arch rib, girder and hangers to determine a reasonable tensioning sequence. The results show: On the basis of satisfying the lateral stability of the arch rib, the tensioning sequence from the two sides to the middle have the smallest stress and reasonable deformation. This study can provide reference for similar bridges.
