Steel Stud Wall at Steel Beam
Steel Stud Wall at Steel Beam
(OP)
I recently had gone to a job site to measure some existing joists since we are going to have some new mechanical units on the roof. The steel beam supporting the joists has some vertical steel studs at the exterior. They are not sitting on the beam flange but they are attached (welded) to the beam with angles (cont. one each at top and bottom of the steel stud). Also these steel stud walls seem to have channels at about 4'0" o.c within the wall at the openings (window/door) in the steel stud wall. The end of the openings themselves are supported on steel channels. I am just wondering whether this scenario would introduce any dead load on the steel beam or these loads due to the stud walls will go directly to the foundation. Does it depend on how the construction sequence was?

If I understand your description, not only will you have dead load on the beam from the studs/wall/doors/windows, but you might have torsion on the beam as well since you imply that the angles are welded away from the centerline of the beam.

I am attaching a sketch as per the site condition.

If the studs are not supported by foundation, they will hang eccentrically from the beam causing flexural and torsional stresses in the beam.

I am looking at adding a mechanical unit on roof that is supported by the wide flange beam. Do I need to worry about the beam ?

Try to model the situation if you must, but i would think that angle should be taken out and some sort of clip that allows vertical movement be installed in its place. This all depends on how it was designed in the first place though.
