Abstract:

The design of the bridge located in a city will be positioned as a landmark building at the entrance to the city, and also an important part of the urban road or highway, which has an important role for strengthening the city and the external connection and promoting the urban development. A five-span half-through double-ribbon tensional arch bridge is innovatively proposed. The "double-ribbon" design is adopted in the modeling, and the bionic concept is introduced into the bridge to make the design more vital signs. The design of the bridge strives to meet the requirements of functionality and usability, and fully considers the architectural and landscape factors, which make it a landmark building at the entrance to the city.
