It is common that post-installed anchors encounter locations in the concrete where reinforcement interferes with their installation. In some cases, the initial hole can be discarded, and the anchor re-installed where reinforcement does not interfere. On the other hand, there are many cases where the prefabricated fixtures do not provide this flexibility and costly modifications are required. Furthermore, it is common that cast-in anchors encounter location tolerance challengers and are often discarded for a post-installed solution.
This paper will investigate the seismic shear testing of both post-installed and cast-in anchors when mitigating the tolerances issues using a commercially available device.
