Studies on Evaluation Methods for Creep Deformation of Bonded Anchor

Abstract

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 :
