Long-slotted and short-slotted?

[ForrestLowell]

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

There sure are a lot of questions regarding the original very simple question: Can you put a SSL hole in one ply and an LSL hole in another ply in the same connection? The specification doesn't seem to address it specifically. It doesn't forbid it, as best I can tell. You could e-mail AISC's Steel Solutions Center and get their opinion.

nutte,

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!
