Form-finding study of Taizhou Bridge A 3-pylon suspension bridge

In this paper, The special feature of 3-pylon suspension bridge is introduced and the formfinding study of Taizhou Bridge is carried out. Because of the existing middle pylon, 3pylon suspension bridge show a difference characteristic with the 2-pylon suspension bridge. In order to find better form results for the main components, topological optimization method and the force tracing method was applied for the form finding of the bridge. Combined with other modeling method, the topological optimization method and the force tracing method proved to be an effective way in the form finding study.
