| Research Abstract |
We studied how to get reasonably strengthening effect for reinforced concrete beam which deteriorated by rebar corrosion by strengthening with a continuous fiber sheet. As a result, the corrosion mass loss ratio of the longitudinal bars is at about10% or less, even if the continuous fiber sheet without repair of the host metal, indicating the possibility that an adequate structural performance recovery can be expected. Meanwhile, the corrosion amount of longitudinal bars becomes more than 30%, it wasfound that do not have a sufficient strengthening effect without repair of the host material such as the patch repair.
