| 摘 要： | 在FRP加固钢筋混凝土梁抗剪试验的基础上,系统地总结了已有的FRP加固钢筋混凝土梁抗剪承载力计算方法。通过与大量试验数据的比较,指出了已有计算方法的不足之处。在统计试验梁试验结果的基础上,综合考虑开裂角度、配箍率、剪跨比的影响,对Ahmed的有效应变计算模式进行了修正,提出了修正的FRP加固钢筋混凝土梁抗剪计算模式。经过与试验值的对比,证明本文提出的修正计算模式与试验值吻合良好。

| Abstract: | Some calculated methods of shear capacity of RC beams strengthened with FRP(fiber reinforced polymer) are reviewed based on the experimental data on shear capacity of RC beams strengthened with FRP.The exiting shear strength models of RC beams strengthened with FRP are compared with experimental data and the distinct deficiencies are pointed out.Taking into account the effect of crack angle,ratio of transverse steel reinforcement and ratio of shear span to effective depth,the Ahmed's effective FRP strain model was modified based on experimental results.A modified calculation method of shear capacity of RC beams strengthened with FRP was presented to predict the shear strength of RC beams strengthened with FRP.The calculated results show the proposed method has shown close agreement with the experimental results. |
