RE: SEISMIC ANCHORAGE

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Good morning Steve,
Could you be a little more specific.
What code changed, what eliminated the ability to use epoxy for
anchorage of all thread rods?
Is this an IBC thing or UBC or other?

Subject: SEISMIC ANCHORAGE

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,
 
V. Steve Gordin, SE
