The transfer length of a deformed bar used for prestressing steel in a pretensioned prestressed concrete was investigated. The transfer length test and the tensile reinforced concrete prism test were performed, and the bond-slip relationships were obtained from both tests. The bond-slip relationships of the prestress transfer bond was similar to that of the bond in the tensile prism, but signs in the relationship equations were reversed. For practical use, the transfer lengths of the deformed bars were calculated using the tensile bondslip relationships.
