Slip Critical Connection
(OP)
Can you specify SC connection if the bolts are subjected to tension? For example hanger connection?

RE: Slip Critical Connection
RE: Slip Critical Connection
Are the bolts only under tension, as in there is no shear on them? If so, why would you call out a slip critical connection?

Can you tell me where I can find this equation?
Thanks
RE: Slip Critical Connection
Certain types of connections usually should be SC - such as bolts in direct tension. I think it was worded directly as such in the 9th edition but the 13th seems to have an overflow of commentary, essentially leaving it up to the EOR whether to pretension or not.
RE: Slip Critical Connection
Is that right?
RE: Slip Critical Connection
If the bolt is A325, you're not required to pretension it, although it is probably a good idea to. However, there is a difference between pretensioning a bolt and a slip critical connection. Calling for a SC connection requires surface preparation in addition to the pretension. If you just want a fully torqued bolt, call it out that way.
