moment connection details
(OP)
Sorry if this has been asked already. What details do you guys use for moment connections? Specifically for beam to beam connections. I've been using the standard one from the AISC 9 manual like in Detail 1 of the attached sketch. For beams to columns, I really like welding end plates to the beams and bolting them. So I was thinking, would it maybe be better to use something like Detail 2 for beam to beam connections? I would think it would be easier to erect, at least for new construction, because all the welding can be done in the shop. Can you think of a reason it wouldn't be any good?
Also, share any other clever details you like to use.
Thanks

yes, like poster above, you need another beam on the other side to counter torsion.

If you have structural software try modeling a fixed-fixed beam framing into to cross beams. You will find that even when you make the cross beams large, you generate almost no fixity at the connection due to the torsional flexibility of the cross beams.

All in all, I'd say it's a lot easier (and cheaper) to add a member on the other side which resists the moment.
