| 摘 要： | 对纤维增强复合材料(FRP)片材抗剪加固钢筋混凝土梁的研究现状进行了回顾和总结,归纳了FRP的抗剪加固方式,包括粘贴形式和锚固方法;将影响加固效果的主要因素概括为原梁条件和加固参数两大项,并讨论了若干分项因素的影响;探讨了加固梁的抗剪机理和破坏模式,列举了各国技术标准提供的和相关文献建议的多种抗剪承载力计算方法;指出了加强FRP片材端部锚固的重要性以及有待拓广和深入的应用基础研究方向,可为后续研究提供有益的参考。

| Abstract: | The state-of-the-art research on reinforced concrete(RC) beams shear-strengthened with fiber reinforced polymer(FRP) laminates was summarized and reviewed.The shear-strengthening way,including bonding configuration and anchorage method,was summed up.The main factors of affecting the shear behavior were generalized and classified respectively as beam parameters and strengthening ones.The shear mechanism and the failure modes of the strengthened beams were discussed.Meanwhile,several kinds of calculation meth... |
