摘要
利用数值分析方法成功地计算出了钢管高强混凝土压弯构件在不同加载路径下的荷载－变形全过程关系曲线，较深入地研究了这类构件的力学性能，理论分析结果与试验结果吻合得令人满意。研究结果表明，随着核心混凝土强度的变化，钢管混凝土压弯构件的力学性能变化是连续和统一的。
Integral method is applied for the calculations of complete load-deformation curves of high strength concrete filled steel tubular compression-bending members under different kind of loading paths,the behavior of this kind of members are analyzed,and the theoretical results fit with those of tests satisfactorily.The researching works show that the behavior of concrete filled steel tubular members subjected to compression and bending moment is continuous and unitive with the rariation of core-concret′s strength.
