Can a seat connection (stiffened or not) resist torsion?
Can a seat connection (stiffened or not) resist torsion?
(OP)
I have a beam spaning between two columns 14 OC that supports two (2) pipes. The pipes move due to thermal expansion and contraction and even thought the friction has been reduced, it is still high enough to induce some torsion. The question is: Can a stiffened or unstifenned beam connection resist any torsion?
Thank you
Thank you

If you could add a top plate or angle, I think you'd be in business.

The connections has been made with a thick top angle bolted to concrete with two (2) anchor bolts and not the otional side clip. However, I am planing to add a stiffener to the seat angle between the bottom concrete anchor bolts. Flexibility of the connection is not that critical.

usually in pipe rack design the moment caused by pipe friction is neglected because it will be counter acted by the weight of pipe.

If that is what we want, I dont see a problem replacing it with a double clip angle connection. I was just concerned of what will happen to the beam when the pipe starts moving. Is it going to remain vertical or it will start twisting? However, I tend to agree with westheimer1234 that the twisting will be counteracted with the much larger dead weight load.
Thank you all.
