| Abstract: | The results of pure-bending experiment on concrete filled steel tubular（CFST） member with dumbbell shape indicated that it has favorable property on plastic-elasticity and tensibility.The change law on the relationship between deflection-load of CFST member with dumbbell shape has been analyzed,from which the experiment data about flexural rigidity in different force phase are obtained.Based on the above,a simplified method is proposed to calculate the flexural rigidity of CFST member with dumbbell shape. |
