Re: SEISMIC ANCHORAGE

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Robert,
 
The change in testing procedures is quite sweeping (refer to Ben Yousefi's post), and affects both the IBC and UBC.  Please refer to http://www.icc-es.org/reports/pdf_files/UBC/5369.pdf, Table 5.  Similar provisions now exist for all other HILTI epoxy anchors.  Moreover, according to HILTI engineers, it is also so for similar anchors of all their competitors (this is why HILTI is not that worried about such condition).  Looks like we are left out in the cold...

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?


Robert Randig, P.E.

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,
