초록

This paper presents the experimental results on the development length of FRP tendons by direct pullout test. Two types of FRP tendons, namely, CFCC tendon and KICT tendon, and PS tendon were investigated. The development length defined as the minimum embedment length required to develop the ultimate tensile strength was suggested using the test results. It was found that the development length from the direct pullout test was greater than those of various standards. This may result from the fact that the wedge effect does not exist because there is no prestressing force in the direct pullout test. Further study and experiment are necessary to derive the reasonable development length for FRP tendon.
