Kootk, So saying "Attach steel deck to steel beam per general notes is not sufficient" in your opinion. What about the buildings that are already built (4-5 years old)? We did not get such an RFI before. It started happening in the last 6-7 months.
The joists bear on the exterior walls like the beam. The joists and beam are parallel to each other. The detail shows steel deck sitting on the top of steel joists and steel beam. The regular spacing between the joists is 6'-0". The beam also acts as a joist. The beam is in between the two...
We have prototypical steel buildings that has steel joists at 6'-0" o.c. We have an interior brace frame that lies in between two joists. In our details, we have that shows the location with both the steel beam and steel joists. We specifically say that the steel deck to attach steel deck per...
We are designing a residential building in a heavy snow area. The maximum load on the roof (snow+drift+dead) is about 150 psf. Per the IBC, tables 2304.7(3) and 2304.7(4) the maximum load I see is 100 psf (table 2304.7(3)) for 3/4" sheathing.
Is plywood not possible for the loads?
I am...
I am helping in the design of a three story wood building. We have a wood stair at the exterior wall at one end. I am trying to understand the detailing aspect of the stairs in terms of the top plate height. Generally, we show a top plate height at the mid landing and then the top plate height...
Thanks for clearing my doubt. I am bit confused due to welds that are on the shops at another location for a similar condition. The plate this time is 1" plate. The shop drawings shows a fillet weld along the length/height of the column. The plate is wider than the column. I understand that it...
The plate is attached parallel to the web of the tube. Isn't this a lap joint?
Or since the "edge" is of the 3/4" material and face is of the tube wall, the edge of the 3/4" plate governs?
We have two situations on project where a 3/4" plate is welded to a tube section on its face. The welds are oversized (more than our calculations). For example, at 3/8" tube wall has a 3/8" weld on its face and a 5/16" tube wall also has 3/8" weld on its face. This is against the code I...
It seems the change is very recent. We have the old document from the city that shows the 40 psf ground. We will design the new building for 40 psf roof. We will keep the old design document from the city for our records.
