| 摘 要： | 推导出轴心受压圆截面钢-CFRP-混凝土组合短柱中混凝土、CFRP管和钢管各方向上的应力与轴向压力之间的关系式，掌握轴心受压时组合短柱内部的受力情况。根据弹性力学理论中的厚壁圆筒分析理论、薄壁圆筒分析理论及变形协调关系分析在轴向压力作用下圆截面钢CFRP混凝土组合短柱的受力情况。由所推导出的公式可见，在线弹性范围内组合短柱各部分所受的应力与组合短柱所承受的轴向压力成正比，并与钢管和CFRP管的厚度、弹性模量、混凝土的截面尺寸、泊松比、弹性模量有着密切的联系。 |
| 关 键 词： | CFRP 组合短柱 轴心受压 变形协调关系 |

| Abstract: | Derive the stress of all directions and the relation between the axial pressure of concrete,CFRP tube and steel pipe in the axially loaded circular section steel-CFRP-concrete composite short column.Analyze the force of circular section steel-CFRP-concrete composite short column under the axial pressure according to the analysis of thick-walled cylinder theory,thin-walled cylinder theory and deformation-coordination relation in elasticity theory.From the derived formula we can see that in linear elastic range,the stress of all the parts of the composite column is proportional to the axial pressure suffered by the column. |
