介绍了钢管混凝土的受力特征，然后，在确定了钢材和核心混凝土应力-应变关系模型的基础上，利用有限元软件ABAQUS建立了钢管混凝土力学性能模型，通过ABAQUS软件模拟得出了各构件荷载位移全曲线，以及各个构件的承载力状况。最后，把模拟结果与试验结果进行了对比。结果表明，该有限元模型可以很好地模拟钢管混凝土中核心混凝土自应力及承载力工作机理。

It presented a study on the mechanical behavior of concrete-filled steel tube. First,briefly introduced the concrete filled steel tube mechanical characteristics. Then the stress-strain relationship of steel tube and concrete core was identified,and a finite element model on the mechanical behavior of concrete-filled steel tube was developed using ABAQUS. Load-displacement whole process curve and bearing capacity status of each component were got through using ABAQUS software. Based on the comparison between the results from finite element analysis model an tests. The results show that the finite element model can well simulate self-stress of core concrete and bearing capacity working mechanism in concrete filled steel tube.
