Abstract

Abstract

To reflect more intuitively steel and concrete' s contributions to total bending rigidity of concrete-filled steeltubular( CFST), bending mechanical property of five CFST free beams were tested, the results and other test resultsfrom relevant literatures were handled with linear regression method to research the reduction factor of superpositiontheory which can be used to calculate CFST bending members' bending rigidity．The result showed concrete inrectangular and circle CFST had greater contribution to total bending rigidity than that in square CFST．Finally, theapplication scope of several common standards was discussed according to the regression results．
- concrete-filled steel tubular,
- bending mechanical property,
- linear regression method,
- bending rigidity,
- reduction factor
