摘 要: 简述加固混凝土梁纤维复合材料 (FRP)性能发挥效率较差、加固梁延性较低的主要原因 ,说明提高FRP性能的利用率、改善加固梁延性的途径是 :梁端FRP锚固、沿梁长粘结加压和使用混杂纤维复合材料 (HFRP) ;并初步探讨简易实施方法。 The main reasons why fiber reinforced polymer(FRP) of strengthened beams performs a low efficiency and the strengthened beams exhibit a poor ductility are discussed.It is shown that the ways for increasing the efficiency of FRP and improving the ductility of the repaired beams are anchorages of the FRP at the ends of a beam,bond pressure along the span of a beam and using hybrid fiber reinforced polymer(HFRP).A simple construction method is discussed initially.
