Long-slotted and short-slotted?
Long-slotted and short-slotted?
(OP)
AISC 13th edition (Black book) pages 16.2-21 states that short slotted holes can be used in both plys of a SC connection. it also states that a long-slotted hole can only be used in one ply of the SC connection. My question is, can I use a long-slotted hole in one ply and a short-slotted hole in the other ply of a SC connection? Anybody with experience in this?
Thanks for the help,
Forrest

I am mostly just curious.

I am having a difficult time understanding the situation.

Michael.
Timing has a lot to do with the outcome of a rain dance.
RE: Long-slotted and short-slotted?
Regardless of your application, this is an interesting question worth to understand. Can you post a sketch with space constraints and direction of intend member movement.
I doubt the code would permit it, but maybe there are other alternatives.
RE: Long-slotted and short-slotted?
I would also think that if the SC is specified here it would be for servicability, not strength.

What is the purpose of both of your long slots, does that have anything to do with erection? Can't you get away with one ply STD and the other LSL?

For a 7/8" dia bolt I believe a long slotted hole is
2 3/16" long. That should allow for a considerable amount of play. Again, a sketch might be some help.
RE: Long-slotted and short-slotted?
I do think you can use Long slots on SC joints regardless of direction of loading, no?
RE: Long-slotted and short-slotted?
Yes. You are right! :)
Why would anyone need two long slots, or one SSL and one LSL? I am mean what kind of application would that be? In what I've dealt with there would always be a combination of STD and SSL/LSL.

How much room is that? I mean, ~2 in. for every connection in the siding... sounds a little bit crazy, but what do I know...
RE: Long-slotted and short-slotted?
No doubt it is a lot. Sounds like he has a connection that requires a lot of capicity but with limited room to work.

That is true as well. If it doesn't forbid it, it is most likely of no concern... However, maybe you could use 1" dia. bolts instead of 7/8, and use 4rows 2 columns, LSL slots.. I think, no? Well good luck.
You know I've posted a question regarding Yield Line Analysis in column flanges, if anyone here has a comment please feel free to do so!
