The tensile creep test of the post-installed anchor was carried out by the improved spring type creep test equipment. The measurement of creep deformation from non-load and creep fracture time was possible over a long period of time by this equipment. The creep deformation at about 1/3 load of the maximum load increase slightly for the duration of 90 day, but the creep deformation is very small, and creep fracture will not occur in 50 years. And at 80% of the maximum load, creep fracture occurred in 168 days.

In this study, creep tests for cast-in-place anchor, inorganic and organic types of post-installed anchors were conducted. For the inorganic-type anchor, creep characteristics were evaluated in accordance with EOTA ETAG 001 Part5. Creep deformation amount of long-term from the creep curve has been estimated by the exponential and logarithmic functions. In loading period 50 years, the value estimated by an exponential function is 1.3 times larger than the value estimated by the logarithmic function. The slope of the estimated equation from the creep failure and the creep curve has become equal by applying a logarithmic function to the inorganic anchors. Keywords :
