| Abstract | This bridge structure was proposed in the first CFST arch bridge in China, i.e., Wangcang Donghe Bridge (Fig.2), which was opened to traffic in 1990. The bridge carries four lanes with a width of 15m and has a main span of 115m. The arch rib has a rise-to-span ratio of 1/6 with a 2m high dumbbell cross-section, which consists of two CFST tubes and two steel webs as well as the filled concrete. The floor system is reinforced and piers are reinforced concrete structures. A D-250cm cast in-situ pile carry the pier column as its foundations. The arch rib was erected by cantilever method with cable crane. Due to the lower cost of substructure and foundation than true arch and the easy erection compared to tied arch, many such bridges have been built after Wangcang Donghe Bridge. Statistics analysis shows in the 232 built CFST arch bridges in China, 30 of them are rigid-frame tied through arch bridges (Chen Bao-chun, 2007). The span of such bridge form is generally 80m-150m. It can reach a large span without side span, as necessary in continuous girder bridge or cable-stayed bridge. Therefore when only a main long span is needed to cross a railway or highway, a rigid-frame tied through CFST arch bridge can be a viable economic solution, such as the Beizhan Bridge (Fig.3) located in GuangABSTRACT: Rigid-frame tied through arch bridge is brought into use with the application of concrete filled steel tube (CFST) arch bridge in China. Development of such bridge type is introduced with some typical bridges. The major issues in design on the structure and the erection are presented. Calculation equations for inner forces of the structure under dead loads are obtained by displacement method. Rigid-frame tied through concrete filled steel tubular arch bridge |
