DETERMINATION OF REASONABLE CONSTRUCTION STATES OF SPECIAL-SHAPED TIED-ARCH BRIDGE

behavior, reasonable construction state Abstract: The special-shaped tied-arch bridge becomes a popular bridge type with the priority to be selected owing to its novel and aesthetic appearance. However, the dissymmetric arch axis diverges a lot from the line of pressure caused by the self-weight of arch and most of bridge engineers are unfamiliar with the construction procedures. As a result, the construction procedure is complex and hard to control and sometimes even dangerous, which limits the application of the special-shaped arch bridge. The Huangbo Liuyang River Bridge casting in place with full framing, which is a special-shaped tied-arch bridge, is taken as a project background to study the structural behaviors for typical construction states and reasonable construction procedures
