| 摘 要： | 通过FRP复合材料包裹RC短柱,从而提高RC短柱的承载力已被众多的工程实践证明是有效的,但FRP约束RC短柱的承载力计算公式却没有统一的规定,存在着许多问题值得商榷.通过对FRP约束矩形柱约束机理的讨论,在现有的本构模型分析的基础上,推导出FRP加固矩形短柱的极限承载力的计算公式,并分析了粘帖层数、粘帖方式、FRP的间距以及倒角半径r对RC短柱承载力的影响. |

| Abstract: | It has been proved valid in practice that FRP combines the concrete to improve the load-carrying capacity of RC short columns.But there is not a uniform provision computing formula to compute the load-carrying capacity of the FRP restricting the concrete and some problems should be solved.Based upon the analysis of existing constitutive model and the discussions with the restrict mechanism of FRP restricting the rectangle RC short column,this paper derives the calculating formula about the load-carrying cap... |
