【Abstract】 The experimental methods and procedures of centrifuge concrete-filled thin-walled steel tubular members under the action of torsion are summarized in this paper.The concept,that there are three phases in the-structure’s destructive process under the action of torsion,is defined by the analysis of the failure mechanism;and the ultimate bearing capacity of this members is presented by the approach of the ultimate equilibrium.On the basis of the data statistical analysis,with regard to the effect of relating calculating parameters,the.formula of the member’s ultimate bearing capacity under torsion can be solved in this paper.更多还原
