RE: SEISMIC ANCHORAGE

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Didn’t Hilti introduce a new anchor to solve this problem?  It is called the HIT-TZ rod, page 91 of the ’05 product technical guide.  According to their Anchor Selection Guide it is may be approved for cracked concrete design.

Good morning.

 

Starting January 1, 2007, all HILTI epoxy anchors are effectively excluded from usage in the areas of high seismicity (UBC Zones 3 and 4, or IBC equivalents).  Apparently, this situation affects all (not only HILTI) epoxy anchors, and the timing to resolve that situation is currently unknown.

 

This means that no ICC reports are currently available to support the engineers decision to use chemical anchors in the areas of high seismicity.

 

Does anybody have the experience of dealing with such situation during the plancheck?

 

Thank you,
