| 摘 要： | 在4根预应力CFRP板加固混凝土梁试验研究的基础上,通过平截面假定以及材料应力应变本构关系进行推导,提出根据确定的目标延性系数反算CFRP板加固面积或初始张拉控制应力的计算方法.计算结果与试验结果比较,计算方法具有良好的适用性,可为实际工程中进行预应力CFRP板加固混凝土梁设计提供参考. |

| Abstract: | Based on the experiment of 4 reinforced concrete beams strengthened with prestressed CFRP plates,an analytical method is derived for determining the allowable plate area or tension control stress to achieve a targeted value of ductility using the plane section assumption and material constitutive relation.Calculational results are compared with experimental data.Comparisons show that the calculation formulas features good applicability,providing a reference for engineering application of strengthening desig... |
