I would like to thank everyone for their advice and comments. You guys have been very helpful.
We obtained allowable local deflections from the architect and from there determined allowable rotations of the W-shape.
W-shapes were used because the owner wished that the new additional structural...
Right. I was informed that the wall finish would be very rigid, but could crack due to any substantial deformations.
I have taken care of local deflections on the wall.
I was worried about the beam rotations because any differential in rotation from beam to beam could cause deformations. I had...
The structure is a large four story atrium-like entrance, but with minimal windows. There is no decking, ect. to tie it back to and no additional framing can be added. The cantilever-wall system is to be cold form shapes with an architectural finish on the cold-form wall frame. The finish weighs...
The wall is running parallel to the beam. The wall is supported by a canilever system attached to the top flange of the W-section. The distance between the centerline of the beam and the center of mass of the wall/wall support system is two feet.
Can anyone provide some guidance on allowable rotations of W-sections for servicability considerations?
I have an architecturally finished wall section being supported by the W-sections. However, the wall is two feet off the centerline of the beam, and is creating a substantial torsional...
