WF-WF lateral connection 1

[WWTEng]

2 W18s, 2'-4" apart. I need to connect the two together to transfer shear from one to the other but the connection needs to allow for vertical movement.

I was thinking of using 2 bent plates, one welded to each WF. Then I would connect the legs of bent plates with A325-N bolts with one leg having a vertical slot allowing for movement. And this is where I have a concern as I am not sure that simply putting a vertical slot will allow for vertical movement. I am confused.

This is a little confusion. Allowing vertical movement and resisting a vertical shear load sounds like a contradiction.

Two parallel beams 2'-4" apart can be interconnected for vertical shear transfer only by putting a torsional moment in each beam. A slotted hole is out of the question.

The whole idea of transferring vertical shear in this situation seems wrong. Or are you talking about horizontal shear?

Perhaps a sketch would clarify what you are trying to accomplish.

Are you actually trying to describe resisting horizontal shear and allowing vertical movement?

 

[WWTEng]

JAE, yes. Transferring lateral/horizontal force and allowing vertical movement. Sorry for the confusion.

What if you tried to make a bearing connection, such that you have to protruding members from one beam, with one protruding member from the other that sits between the other two.

see attached if not clear what I mean.

Use a horizontal brace between the members, hinged at each end. No slotted holes required.
