Long Slots on Double Angle Clip Connection

Long Slots on Double Angle Clip Connection

Long Slots on Double Angle Clip Connection

(OP)
Is there anything in AISC or IBC forbidding the use of long slots on the back-to-back legs of a double angle connection? I have a simple interior carry beam, fairly lightly loaded (~15 kips end reaction), that I would like to isolate from inadvertently carrying any axial load through the frame columns it is framing between. The beam is carrying a simple point load and there is no floor or deck attached to the beam. I am connecting to a thin column web and the bottom of the carry beam is going to be tapered so a single slotted shear plate with a seat and teflon pad is not a real good option here. In my opinion it would probably be overkill. I am curious to hear your thoughts. Thanks!

RE: Long Slots on Double Angle Clip Connection

I don't know if there is any inherent guidance on this, but assuming the worst position of the bolts doesn't exceed eccentricity requirements and you are not using the beam to axially brace your column, then I don't see any issue with long-slots.

RE: Long Slots on Double Angle Clip Connection

Yeah, this condition occurs often at beam connections to concrete walls. This would likely mean that your beam no longer braces the column though.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Thank you for the comments. I would be designing the connection with the loading at the outermost point of the slot and I would not consider this a brace point for the columns.
