    摘要: The suspension bridge has a beautiful structural shape and an excellent spanning ability. The self-anchored suspension bridge has its main cables anchored directly on the two ends of the main girders, saving construction costs and time incurred during the anchorage construction of an earth-anchored suspension bridge. However, the feasibility of a self-anchored suspension bridge in a strong earthquake zone and the use of dampers to reduce seismic responses have yet to be fully investigated.Using the Yellow-River Road Bridge in Mainland as an example, this study sets out to analyze and investigate a series of seismic responses of a self-anchored suspension bridge, with the purpose of understanding its seismic responses in a strong earthquake zone and the effectiveness of metal dampers in reducing the seismic response. In this paper, in addition to performing a linearly elastic seismic analysis, the ductility seismic response was also analyzed. Additionally, metal dampers were installed at the joints of main girders and towers so that the energy damping effect can be investigated. The results of this research will be useful to the academic research community and for practical engineering applications.
