The suggestion of the rational strengthening method for the corrodedRC member and the verification of the re-deterioration phenomenon

研究了如何对钢筋锈蚀破坏的钢筋混凝土梁进行连续纤维布加固，以达到合理的加固效果。因此，纵筋的腐蚀质量损失率约为10%或更少，即使连续纤维板没有修复宿主金属，这表明可以预期适当的结构性能恢复的可能性。同时，纵筋的锈蚀量超过30%，发现如果不对主体材料进行修补，如补片修补，则不能起到足够的加固效果。

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.
