초록
A technique strengthened to the reinforced concrete members using the external post- tensioned method offers the advantages in speed and simplicity of installation over other, established, strengthening techniques. But this technique has many unreasonable facts. This paper are analyzed an unreasonable facts of the previous external post-tension technique. The purpose of this paper proposed Bow system as the new technique strengthened to the reinforced concrete members. The Bow system which is better technique than the previous technique was introduced with the experimental/analytical data.
