Mechanical Behavior of Steel Arch Bridge with Outward Inclined Ribs
Steel tied arch bridge with outward rib was adopted in Aixihu bridge in Nanchang city, in which steel girder width was 73 m. Outstanding features, such as large ratio of width to length, outward inclined ribs, four groups arrangement of spatial suspender existed in this bridge. Beam-column finite element model (FEM) and shell-beam FEM for the arch bridge are established respectively. The mechanical behaviors of the arch ribs and the girder analyzed by two different models are compared. The calculation results show that both beam-column FEM and shell-beam FEM can be used in the analyzing the mechanical behavior of arch ribs, while for the wide girder mechanical character analysis should not depend on beam-column FEM but shell-beam FEM.
