| 摘 要： | 采用有限元软件ABAQUS,对不考虑钢管壁与核心混凝土的粘结,只设置传力构件的矩形钢管混凝土轴压柱进行研究分析。分析核心混凝土及钢管壁的轴力-竖向位移曲线,得出设置传力构件的矩形钢管混凝土柱的轴力-竖向位移曲线及混凝土工作承担系数。通过对轴压作用下设置传力构件的矩形钢管混凝土柱性能的研究分析,验证了可采用CECS159∶2004《矩形钢管混凝土结构技术规程》的相关规定对设置传力构件的矩形钢管混凝土柱的轴压承载力进行计算。

| Abstract: | Using the finite element software ABAQUS, concrete-filled rectangular steel tube column of setting transmission member under axial pressure is studied, without considering the bond of steel tube and core concrete. The force-displacement curves of core concrete and steel tube are analysed respectively, the force-displacement curve of concrete-filled rectangular steel tube column of setting the transmission components and percentage of load- carrying capacity shared by concrete are obtained. Through the performance research and analysis of concrete-filled rectangular steel tube column with transmission components under the axial pressure, it could be verified that the bearing capacity of axial pressure of concrete-filled rectangular steel tube column of setting the transmission components, could be calculated by the CECS 159 ： 2004 Technical Specification for Structures with Concrete Filled Rectangular Steel Tube Members. |
