摘　　要：本文考虑不同加载路径，对钢管混凝土弯扭构件进行了深入系统的理论分析．为了验证理论分析结果的正确性，进行了１２个弯扭构件的试验，结果表明，理论分析结果与试验结果吻合良好．论文最后还推导了钢管混凝土弯扭构件承载力相关方程，从而使钢管混凝土纯弯、纯扭和夸扭构件承载力设计计算公式相互衔接起来，便于实际应用。Systematic analyses for CFST bending-torsion member are done in this paper by considering different loading paths. 12 tests for the CFST bending-torsion members are finished in ode to prow the correction of the theoretical results,and the experimental results fit the theoretical results satisfactorily. Interaction equation of the bearing capacity for the CFST bending-torsion member is deduced in this paper finally, and this enables strength design formulas for bending, torsion and bending-torsion member of CFST to be linked between each other. This is convenient for the practical application.
