Continuous Fiber Rope (CFR) made of Aramid fiber or Vinylon fiber has been developed to apply for the reinforcement of concrete members. It is characterized by a lightweight, a high tensile strength and an excellent durability compared with reinforcing steel bar. It has also a good transportability, and it is flexible to be easily arranged at the construction site.This study aimes to restore a function of the damaged concrete with CFR, assuming that the concrete might be damaged by a big earth-quake or deteriorated by aging or Alkali Silicate Reaction (ASR). In this study, as the first step, the cylinder concrete specimens were made and preloaded up to the compressive failure or the tensile failure. Then these specimens were wound with Vinylon fiber rope in the lateral direction and reloaded up to the failure. From the tests results, the effect of CFR on the damaged concrete was assessed. At the next step, the elastic finite element method (FEM) analysis was executed. From the analytical results, the characteristics of the ultimate state of concrete wound with CFR were quantitatively evaluated.
