    Light Gage Steel Trusses

    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...

    plate girder with corner angles

    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...

    Composite beam with OSB and gypsum board??

    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). An engineer in New Zealand, working...

    Connection of pin based columns with an individual member at base!?

    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...

    Buckling load of a steel stud with eccentricity in codes?

    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 am making the structural design o

    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...

    Stud Alignment in Light Gauge Steel Construction:

    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...

    Screws in Light Gage Steel Framing

    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...

    Semi-Rigid Connection Modelling

    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...
