ABSTRACT
The self-anchored suspension bridge has become a highly competitive design in urban bridge construction due to its beautiful structure and strong adaptability to terrain and geological conditions. Since the saddle are directly supported on the top of the steel bridge pylon, setting up a reasonable structure of the tower to ensure the strength, rigidity, stability of the tower and the smooth transmission of the axial force becomes one of the key issues in the design of self-anchored suspension bridges. This paper uses finite element software to analyze the local mechanical performance of a self-anchored suspension bridge. The calculation results show that the supporting stiffeners under the saddle are mainly participated in the axial force transfer and the force transmission characteristics of the steel pylon in saddle area were summarised to provide a basis for the design of similar structures in the future.
