摘　　要：在离心钢管混凝土构件弹性扭转应力分析的基础上,结合混凝土及钢材强度准则探讨了离心钢管混凝土构件的扭转承载力工程估算方法,计算结果同实验数据基本吻合,为进一步建立简化的工程扭转承载力公式提供了参考。This paper proposes a calculation method of the bearing value of the centrifuge concrete filled thin-walled steel tubula under torsion. The calculation method is developed on the basis of the strength theories, and the formulas of the elastic torsional stress of the member are adopted. Results of the calculation show generally favorable agreement with the data from the related experiment. So the paper presents the theoretical basis for the simplified formulas for practical engineering applications.
