Seismic applications for PAF in cracked concrete

*Posted on behalf of a Hilti customer:

Are there any plans for, or progress being made on developing acceptable use of PAFs in seismic applications in cracked concrete?

Dear Customer,

well this is a good question. ICC acceptance criteria has provided a test method for seismic recognition of PAFs installed in steel. Hilti has tested most of our PAF’s for this application and has received recognition. For fasteners in concrete, no such criteria exists, and it is not allowed by the code for certain structural applications. Hilti has been researching this topic for some time, however there is not currently a code change or new acceptance criteria which is imminent for this application. We hope to work with the industry to change this in the future. Please feel free to reach out any time, if you need additional information.

Cheers
Aidan
