CFRP或钢条带加固砼双向板的承载力分析

采用塑性铰线理论，分析外贴碳纤维布（CFRP）或钢条带加固的正方形板的承载力。改进张继文的塑性铰线模式，得出更为精确的理论解。同时修补了该理论解的一个缺陷，即随着条带宽度的增加，承载力上升至无穷大。与实验值相比较，由于拱的效应，本文的理论解偏于保守。

Analysing the Bearing Capacity of Two-Way Concrete Slabs Reinforced with CFRP or Steel Strips

By adoption of yield line theory, the author analyses the bearing capacity of square slabs reinforced with carbon fibre reinforced plastic (CFRP) or steel strips and improves Zhang Jiwen's yield line pattern. A more accurate theoretical solution is obtained; and moreover, a defect in this theoretical solution, namely, the bearing capacity rises up to infinite with the increase of strip width, is made up. As compared with experimental value, the author's theoretical solution is on the conservative side due to arching effect.
