Abstrait:

Encased CFST (Concrete Filled Steel Tubular) arch structure is an innovative arch structure, in which heavy arch lifting; especially in long span arch bridge is avoided implementing special technique in its construction, as in construction of Wushan Yangtze River Bridge of span 420 m. With the attempt to compute time dependent stresses and deformation due to creep, an experimental creep study is organized on plain concrete, CFST and encased CFST column, and the test result on column member is verified using numerical method. The verified numerical technique is employed to compute creep effect on arch bridges. The results indicate that the crown deflection due to creep is not excessive; the amount will be function of type of concrete, the span of bridge, the dead load of structure and load at transfer. The amount will be less for encased CFST arch bridge compare to RC bridge. A case study made in this paper suggests that Wanxian Yangtze River Bridge’s crown will deflect 16 cm in 3 years.
