Gusset Plate Design
Gusset Plate Design
(OP)
Folks,
Please see attachment calculations and also see attached AISC calcs.
The AISC method used UFM Case III modified and gives results that are slightly different. I know the end result would be 4/16 = 1/4" weld, but there could be a case where the result might be choosing 1/4 vs 5/16.
Can anyone shed some light into it and tell me if I am doing something incorrectly?
Thanks

Could you please explain?
Am I incorrect in applying an eccentricity? The workpoint is at the center of the beam and not at the center of the gusset.
I am fairly new to the UFM method and I would much appreciate it if you could help me understand why there is no eccentricity?
Thanks

Should'nt the Alpha calculation be based on an angle of 42 degrees instead of 48 degrees.

In my calculations (first attachment), I am calculating a moment because I am computing the forces at the workpoint and then moving it down to the gusset interface.
There is no net vertical force on the gusset plate. Only a horizontal force and a moment.

I will need to spend more time to understand the nuances of the UFM.
Thanks for your help. I will need to figure out the difference in results even though I am choosing the same workpoint.
