Though I am at home and don't have the code in front of me, I recall designing with gypsum shear walls before ( with an icc report, i beleive) and I remember that it did not allow an increase in loading for sheathing on both faces of the wall. Hopefully that's a start for you.
Download the SSS 5.0 from The Steel Network. It can analyze studs, joists, etc, and you can set the bridging spacing to the height of the stud which would be effectively unbraced over the entire length.
Typically I show the void-forms generically in the foundation details and call them out per geotech, and on the foundation plan I will call out something like "blah blah slab on x" voidforms per the geotech". Then we will list the geotechnical report information in the general notes. Sorry if...
The presence of void forms below the foundation would indicate high swell potential for the on site soils. This information should be addressed in the geotech report that the engineer of record used for the slab design. See if you can get a copy of the geotech report from the engineer, or see...
When I said I was trying to stay away from proprietary systems I was discretely stating that I didn't want to use the StiffWall system by TSN. Sigma stud is not necessary for bearing on a 2-3 story project as there is typically no cost savings here.
I think I will try to connect a light gauge...
Thank you Mike and Hokie for your responses. Although the plank is heavy, the wall studs at the first floor essentially are the same that you would have with a 9 story cold formed floor system with level rock. The gauge of the studs at the first floor typically come in around 68 mils or (2) 54...
I am designing a 3 story project that utilizes Hollow Core Plank for the floor and roof system and light gauge steel stud walls for the bearing system. The lateral system is to be comprised of sheet steel shear walls.
I have no issue with the connection of the shear walls floor-to-floor, and...
Thank you hokie66. I realize the importance of not penetrating the shaft. My question is how to appropriately connect the stair landing framing to the shaft wall.
I have run some quick numbers and I am finding that the header reactions can get fairly large, especially where there is no...
I have a job where the stair landing headers were detailed to be pocketed in to the walls on either side for bearing. However, after reveiwing IBC Sec 707 I see that penetrations are not allowed in the shaft walls. This particular project requires a 2 hr. rated shaft since it is 4 stories in...
