I need some design examples and procedures about designing cold formed steel trusses (roof trusses to be specific).

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...
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 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...
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...
