Forces in the joint

Forces in the joint

Forces in the joint

(OP)
I have steel moment frame.
Lets say beam is connected to column by welds.

Im wondering what forces are acting on joint - welds and on stiffeners. I dont want to overlook something.






FORCES ON STIFFENER:
- vertical force on stiffner as a beam shear force: V1 = 50 kN
- vertical load form a moment? V2 = M / h1
total vertical load on a stiffener: V1 + V2

FORCES ON WELDS:
- normal forces as a result form bending moments that try to close a corner: M = 70 kNm - N x h1/2 = 70 - 60 x h1/2
- shear forces: V (column shear force)= 50 kN
- axial load: N = 60 kN (compression)

RE: Forces in the joint

These all seem correcct to me.

RE: Forces in the joint

you might want to consider a cap plate on the column with a moment connection. It's likely easier to fabricate and erect and less costly.

RE: Forces in the joint

Have you considered stress in the beam web between the two stiffeners?

I did, tnx.
