Faying Surfaces
Faying Surfaces
(OP)
I am engineering a galvanized or powder coated steel car port parking canopy product that uses a pinned frame system to support a lightweight deck. I would like each connection to be a single 1/2" thru-bolt, but my colleague is arguing that due to the lack of redundancy, he would prefer either two thru bolts (double the hardware cost and install time, relatively difficult to fabricate and install due to angles of the columns) or change to a slip-critical connection (so that in the event the connection fails, there is redundancy in that the bolt will still carry the loads).
I am in favor of the slip-critical connection, but I have no idea how to detail the faying surfaces or how to explain how to fay (?) the surfaces to the fabricator or installer.
Does anyone know where I can find information on how to prepare the surfaces for this connection? Can this be done prior to galvanization or powder coating? Do I have to strip off the protective coating if faying is done prior? If so, are we not concerned about the steel corroding in the fayed areas?
Thanks!!!!!

RE: Faying Surfaces
What does faying mean to you that you are asking the question?

I have no experience with them and I am looking for any information I can find on how to detail them and how to instruct the fabricators and/or installers on how to prepare them in the field.

Also, for all those out there that actually care, there is a moment connection at the foundation, so the bolts that hold the roof deck up would be pinned and the system wont fall down.

I fail to see why you need a pinned connection to be slip critical.
