Seismic Tension Design

When considering the seismic tension design, why are anchors onto hollow CMU walls not permitted in HILTI Profis?

Hi Shaney,

Per Footnote 7 under Table 10 in Section 3.2.4 the Anchor Fastening Technical Guide, HIT-HY 270 anchors are not recognized for resisting earthquake forces when installing into the face of hollow CMU. 

Thank you,
Emily
