Abstract: Concrete creep is one of the basic property of concrete filled steel tube arch bridge(CFST),and have appreciable effect on it. This paper introduces exploitation principle、system functions、realization methods of software about CFST arch bridge ,as well as its preprocessor and postprocessor module,and its finite element mothod computation module.

Key words: concrete filled steel tube arch bridge, creep, software exploitation
