Skewed Beam Moment Connection 5

Hi to all!

I made a search for this topic and could find very little relevant examples/information.

I have a condition where two beams are framing into column flanges. The beams are skewed and carry both gravity and lateral moments. See attached (with flange plates drawn).

The shear loading, V, is carried by the shear plates at beam webs...

1. Any thoughts on how to connect the pieces other than what I have shown?
2. How to avoid torsion in the column? (Used DG9 to check for stresses - NG)
3. The best possible placement of welds?

column W12X96; beams are 24 in deep, Force in Flanges = 133k

csd72,

Upon further reflection, you are correct. There is no torsion in the column at any point because the beams both meet at the centroid of the column...sorry to add confusion to the thread.

I agree about the top of the column (top flanges). Is there is no torsion resulting from the bottom flanges framing into the column flanges, and how so if they are welded?
 
iponom,

hokie66 and csd72 were both correct. The flange plate connection to the column flange cannot produce torsion in the column because the resultant force intersects the column centroid.

I apologize for clouding the issue earlier. My only excuse is I was having a senior moment (not bending moment).

ok perfect. thank you BAretired. you answered my questions completely and very precisely. finally.
 
Reading through this thread almost made my head burst.
I struggled for an hour to see how there was torsion in the column!!!!!! Yinz owe me a beer!!!

As to the tone of the original poster I'll say this:
There are some good guys on this forum whom, on a regular basis, go out of their way to help people they have never and probably will never meet. Hokie and BA (BA loves to argue :) )are a couple of many. I would tread a little more lightly and leave the sarcasm and snide remarks for the bar ...they go over much better there. Plus you may need some advice in the future and I'm guessing you have already told your whole office to go to hell!!! [blush]

 
The OP obviously had a skewed response moment.

Berating Hokie for not giving the answer he thought was correct is just ill-mannered. (Especially when Hokie was correct all along.)
 
Berating anyone on this forum is ill-mannered. It doesn't matter whether or not he is correct.

All parties who responded to this thread truly believed what they were saying at the time they responded, no matter how ill conceived the response they gave (me included).

We can all learn from a forum such as this, but nothing in a technical discussion should be taken in a personal way. Get over it...I'm sure that hokie has.

hokie,

No Fun! you missed your opportunity. you could have convinced your mafia cousins to trace the IP address and .......
