Bolted Connection Design (Punching)
Bolted Connection Design (Punching)
(OP)
I apologize if this was answered in another post but I've searched extensively but cannot find the answer I'm looking for...
I have a design where a square steel plate that is simply supported on two opposing ends. A hole is drilled through the center of the plate to accept a single threaded rod which will be under tension. The load is transferred from the rod to the plate through a heavy-hex nut (and washer if necessary).
I'm trying to determine the punching shear strength of the steel plate in order to help determine an appropriate plate thickness. I understand there is some guidance in the cold-formed manual, but I do not have a copy of that reference.
Any guidance or insight is appreciated as always.

Punching shear is similar to shear yielding and the criteria shown in AISC 13th Ed. for HSS connections.

How thick is the plate?
What is the rod diameter?
RE: Bolted Connection Design (Punching)
Vr = 0.55φwdFy
where w is the perimeter of nut or washer and d is the depth or thickness of plate.

I'm surprised that AISC would be of the opinion that this isn't an issue, especially since it is discussed in other codes such as CSA.
