Abstract:The main bridge of Conghua Bridge in Guangzhou is a single-span 136 m through concrete filled steel tube spatial arch-beam composite system bridge, and belongs to an unconventional structure. The joint anchorage design of suspender and arch rib, suspender and main beam is one of the key control points of the whole design scheme. In order to obtain a reasonable design scheme of suspender anchorage and ensure the structural stress safety, various possible joint connection schemes suitable for Conghua Bridge are listed, and the advantages and disadvantages of the schemes are analyzed and evaluated one by one. Finally, the scheme adopted by this bridge is given.
