RE: ACI 318 App D, and wedge anchors

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hilti and Simpson have ICC evaluation reports for expansion bolts based on the new criteria.
When dealing with uncracked concrete in low seismic regions you may find the older expansion bolts still meet the criteria.
An ICC evaluation report should not be needed for expansion bolts tested in accordance with ACI 355.  ACI 318 addresses expansion bolts and references ACI 355.  Thus as long as you have a test report that shows compliance with ACI 355 an evaluation report should not be needed.  
There are only two reasons for evaluation reports 1) to help convince the building official to allow you to use a product not addressed in the building code, or 2) to give you and others a good feeling about the product.  If you can show conformance with the standards referenced in the code then the building official cannot legally say no.
There really is very little difference between an expansion bolt and a high strength bolt.  With the expansion bolt all that we need is a certification from the manufacturer.
If you are dealing with epoxy anchors only Hilti has an ICC evaluation report covering seismic and cracked concrete.  Simpson is in process of doing the testing and should have a evaluation report in the next month or two.
