摘　　要：通过深入分析目前的钢管混凝土的计算理论以及纤维模型法在矩形钢管混凝土纯弯构件中的应用,利用Fortran语言程序,得到矩形钢管混凝土纯弯构件截面曲线的简化计算模型,该计算模型的承载力计算结果与数值计算的结果吻合很好,可应用到框架的受力分析中.Calculation theory of concrete -filled steel tubes was concluded and summarized. The application of fiber model method to concrete-filled rectangular steel tubes subjected to pure bending was introduced. Simplified calculation model was developed by using Fortran. Moment-curvature formula of concrete-filled rectangular steel tubes subjected to pure bending was proposed. And the calculation results using this model tally with the numerical analytical results.
