RE: Post-Installed Anchors - again

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Nope! Seems like we are stuck with special inspection for all post-installed mechanical anchors, although if it were shear only and the unity factor was less than 50% you might be able to convince the building dept. to waive it, but probably wouldn't happen.
Larry, (again)

Thanks for the replies.  The other PITA with all this is the requirement for continuous inspection in every ESR Report I've seen.  Anyone been able to get relief for that?

I think you are right- but why go through the manual calculation when there are all of the free post-installed anchor software programs out there, (Hilti, Simpson, Powers)? They have made the codes so complicated that you are more likely going to miss something trying to do a hand calc than inputting bad info into a software program.

In addition, there is special inspection.
