Post-installed anchors are used in many existing concrete structures to construct additional members. The purposes of this study are to investigate the bond strength, pull-out bearing capacity, and torque of a post-installed screw anchor with the epoxy resin adhesion. In this study, the single anchor was installed into concrete slabs. The test parameter was the embedment depth. From the results of the pull-out tests, firstly, the bond strength was obtained. Secondary, the pull-out bearing capacity failed in the cone failure mode was estimated based on the empirical equation proposed by Fuchs et al. Furthermore, from the relationship between the pull-out bearing capacity and bond strength curves, the pull-out bearing capacity in the combined failure mode was safely estimated applying the intersection value at the depth of the bond failure. Finally, the correlation between the pull-out bearing capacity and the torque was revealed to be the linear trend in the relatively short embedment depth of anchor.
