| 摘 要： | 为分析菱形截面Rc柱在轴心受压时的受力特点，利用有限元软件ABAQUS，按照截面形状的不同建立了5个菱形截面Rc柱模型，完成了轴心受压时构件荷载一变形全过程曲线的计算。计算结果表明，当截面夹角α小于70°时，构件轴心受压承载力及延性有明显降低。

| Abstract: | Using finite element software ABAQUS,5 models of diamond Reinforced Concrete （RC） column with different section was built to analyze the stressing feature of the diamond section RC columns subjected to axial compression. The load-deformation curves were calculated under axial compression. The results of calculation show that the bearing capacity and ductility of the columns is significantly reduced when the section angle α is less than 70 degree angle. |
