Moment resistant slip critical connection

Moment resistant slip critical connection

Moment resistant slip critical connection

(OP)
Hi, wondering if anyone can help clarify the proper way to analyze this type of connection.

Say you have a bolted connection resisting moment which is putting a tension force on the bolts. Bolts further away from the connection centroid see a higher tensile force than those closer to the centroid or bolts in the compression side of the centroid.

The connection is also subject to shear force and must be a slip critical connection.

So you analyze the bolt furthest from the centroid of the connection to make sure it can handle the combined shear and tension load.

Now you have to check to make sure the connection is slip critical...this is where I have trouble.
Do you check the bolt furthest from the centroid of the the connection again?
Specification for structural joints in the steel manual has a blurb on pg36 saying

>For most applications, the assumption that the slip resistance at each fastener is equal and additive with that at the other fasteners is based on the fact that all locations must develop the slip force before a total joint slip can occur.

Does this mean you only need to check the bolt seeing the lowest shear/tension force? And if that one passes then the connection is slip critical? This is not what I would have thought but I am looking to see if anyone can point me in the right direction.

Thank you very much for your time.
