State of the art of creep of concrete filled steel tubular arches

The state of the art of creep of Concrete Filled Steel Tubular (CFST) arch bridges including CFST members is presented in this paper. It is delineated that researches on creep of CFST is not mature and need much study compare to creep of plain concrete and reinforced concrete. In comparison with the plain concrete members, creep magnitude in CFST is relatively low but, the duration is longer. Creep has much influence on the deformation, stress redistribution between steel tube and core concrete and to reduce the buckling strength of CFST arches; how to implement the research results on actual arch bridge design is necessary part of research in pending. A good creep prediction model is the urgent essence of today’s design works with CFST element.
