ABSTRACT
The creep deformation of ultra-rapid-hardening cement-type post-installed bonded anchor was studied, and the influences of the sustained load magnitude, deformed bar diameter, and anchor type were examined for an embedment length of seven times the nominal diameter. To investigate the influence of the sustained load magnitude, sustained loads were applied at magnitudes of 0.33 to 0.95 times the ultimate load magnitude. In each test, the load magnitude and the displacement of the anchor at the free end were measured. For the influence of deformed bar diameter, D13 and D19 reinforcing bars were used for the anchors. And the three types of anchors were prepared: the Cast-In-Place anchors (CIP), the inorganic-type Post-Installed Bonded anchors (InPIB), and the organic-type Post-Installed Bonded anchors (OrPIB).
