| Abstract: | 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. |
