| 摘 要： | 外包钢混凝土结构构造简单、联接方便、承载力高、延性好。但作为受弯构件,其抗裂性能及抗弯刚度等优势不是很明显。对其施加预应力,形成有粘结预应力外包角钢混凝土结构,可以进一步提高构件的承载能力、抗弯刚度、抗裂性能、耐久性。文章对有粘结预应力外包角钢混凝土梁进行施工阶段弹性受力分析,并给出其相应应力、应变计算公式。

| Abstract: | Steel encased concrete has simple structure,high capacity and good ductility.It is also easy to join with other construction part.If it is pre-stressed,the structure made of such concrete will has more capacity,flexural stiffness,crack-resisting performance and better ductility.The elastic load analysis of cohesive pre-stressed angle steel encased concrete combination beams during construction was performed,and formulae of stress and strain are given. |

| Keywords: | pre-stress angle steel encased concrete stress strain |
