摘　　要：采用数值积分方法模拟计算了钢骨-钢管高强混凝土压弯组合柱的荷载-变形关系曲线,计算结果得到了试验的验证。基于数值计算结果,研究了影响钢骨-钢管高强混凝土压弯组合柱承载力的主要因素,并给出了压弯组合柱承载力的简化计算公式。The numerical method is applied to simulate the load-deformation curve of steel tubular column fiUed with steelreinforced high-strength concrete subjected to compression and bending. The numerical results are verified by experimental data. Based on the numerical results, the major factors influencing bad-bearing capacity of the composite column subjected to compression and bending are studied, and formulas for predicting load-beating capacity of the composite column are proposed.
