What kind of screw are used to fix the strap to the studs ?
I am going to put a board directly to the metal studs so they should be like countersunk screws , or is it a common practice to drill and pop rivet these straps if the board is going to be applied on the frame ?
I need some design examples and procedures about designing cold formed steel trusses (roof trusses to be specific).
Or i would be very happy if someone could mail me some design examples (a word document or a number of scanned pages or anything... ).
Do anyone know a web page or a book where i...

Hi,
I have seen a plate girder with 25m span, 80cm total height, 5cm X 60cm flanges, 2.5cm X 70cm web. And four corner angles of same dimensions are used at top and bottom of the web. The flanges are made up of 2 2.5cm thick plates which are bolted at certain intervals.... I wonder if the corner...
Thank you very much DaveViking. Your reply has been very helpful. More or less i thought the same way as you wrote. But i have seen a picture (just a picture nothing more) of a beam whose web is OSB (i don't know its height but 20-30cm approx.)and there are two timber rectangle solid blocks at...
Hi, happy new year for everyone...
I want to learn if anyone has utilized OSB (oriented strand board) as a load carrying member? I mean as a flange of a cold formed C shaped member, or as a web of two plywood members (screwed/glued at top and bottom of OSB).

Once in a project during the construction of a 2 storey steel residential building, one of the owner's of the
houses (he was an architect by the way) suggested that all the columns should be connected by a U
section (with enough thickness (?) ) all around the building at the floor level only...
I have a wall panel with light gauge thin walled studs with 0.8cm^2 effective area and KLx =1m KLy=1m KLt=1m . It is used to support the load coming from several shelves (if uniform distribution is assumed 330kgf acting on stud). The panel and the shelves above it are moved several meters...
I did not receive satisfactory replies for my previous question. So i decided to post it as another forum.It is very important for me. Here is my problem:
In “Prescriptive Method for Residential Cold-Formed Steel Framing” there is a restriction for alignment of the structural framing. The...
I know allowable loads for plywood or OSB shearwalls with metal studs. They are freely available on the web page:

But I did not receive replies to my questions yet....(except
ishvaaag, thanks...)
I am making the structural design of a light gauge residential building with 1.5 storeys. All inner and exterior walls are load bearing walls. I may choose to make inner walls only carry loads in vertical direction. But i have difficulties in disributing the lateral loads. The inner walls are...
In “Prescriptive Method for Residential Cold-Formed Steel Framing” there is a restriction for alignment of the structural framing. The distance between the centerline of the wall stud and that of the floor joist is restricted to be no more than 0.75 inches. We are using a rollformer machine and...
The nominal screw shear strengths for both AISI and NZ Code are very close to each other. But in AISI the resistance factor is 0.5, in NZ Code it is 0.9. The governing vertical load combination is same in both of these codes : 1.2DL+1.6LL. What is the reason for this difference? One of the codes...
Thanks for the last reply. Now we are talking about same things. Yes i have a light gauge small structure with 2-3 stories. And yes my structure is thin walled.
1. I agree that it is very very difficult to make rigid connections in my case. But some reasons forced me to think about it.
2. I...
To IJR;
Thanks for your reply. It was very helpful. But i think i could not made myself clear at some points. I do trust welding at site but in my case both the beam and column are C shaped with 3mm thicknesses. Assume the weld is done perfectly at the side still i can not weld both sides of...
To Ishvaaag;
Thanks for your reply. I should have mentioned some other properties of my situation. First we don't use masory walls or concrete walls. The usual practice is using OSB (oriented strand board) for siding of the structure. Wall studs with 60cm spacing is used to benefit from the...
Maybe this question will be longest ever in this site. Sorry for that.
I am working as the only civil engineer in a company specialized in cold formed residential steel structures. We are designing structures with 2-3 stories. I have graduated in 2000. I did not worked with an engineer since my...
