The question has to do with the REVCLOUD in the attached file. I'll type some notes and send them while the file is uploading.
Customer reply replied 2 years ago
Please notice the 'new room' on the left hand side of the drawing and the 'new comm closet' near it. These rooms are framed with light gauge steel studs to a height of 8 feet.Toward the right hand side of the drawing are two cross sections, one for each room. Originally the plan showed these rooms to be braced with alternating 45 degree braces at the top, attaching the new walls to the underside of the roof deck approximately 3-4 feet above. Due to the HVAC trunk line near the 'new room' we could only brace one side, and did so at 16" o.c. We did not brace the 'new comm room' walls or the short wall on the 'new room' as they were very short lengths and the carpenter didn't feel it was needed.The inspector said he would accept it if the architect modified the print to show that our 'as built' was acceptable. As you can see, the architect drew the changes but added language that says the modified construction must meet certain stresses. I've contacted the manufacturer but I only get pointed to the ASTM recommended guidelines for bracing, which unfortunately I don't have and frankly are a bit beyond my knowledge base.Can you tell me if the revised bracing is in compliance with ASTM C754?
Structural Engineer: StructuralEng, Consultant replied 2 years ago

Unfortunately, that bracing is not stable.

Structural Engineer: StructuralEng, Consultant replied 2 years ago

Meaning it doesn't stabilize the top of the wall.

i need to figure out a way to brace around the HVAC duct? If I were to install diagonal bracing at a decreased angle (say, 22.5 degrees) on the duct side, along with the 45 degree bracing on the other side, would that work?
Customer reply replied 2 years ago
I assume I should brace the short walls also, correct?
Structural Engineer: StructuralEng, Consultant replied 2 years ago

A single diagonal won't work. That is not a stable solution. You will need two diagonals coming to the top of the wall. Make one as vertical as you can and do the other at 30 degrees, give or take

Ask Your Own Structural Engineering Question
Customer reply replied 2 years ago
Ok. I already have the diagonals on one side at 45 degrees. I'll install the others at as close to 30 degrees as I can get.Can you send me an except of the ASTM standard that indicates this is acceptable? I'll need to show it to the inspector.
Customer reply replied 2 years ago
I have to step out for a few minutes. I'll check back later.
Structural Engineer: StructuralEng, Consultant replied 2 years ago

That doesn't address bracing layout. Bracing layout is about making sure it's stable. If the one in place is near 45 degrees then install the next one as close to vertical as the duct will allow

Ask Your Own Structural Engineering Question
Customer reply replied 2 years ago
Okay, I understand about the ASTM document. I should have asked the more appropriate question, "Can you provide me with some documentation that supports what the architect is saying in the REVCLOUD?"
Structural Engineer: StructuralEng, Consultant replied 2 years ago

To take the 5 psf load?
