COLD FORMED STEEL DESIGN with RAMADVANSE
COLD FORMED STEEL DESIGN with RAMADVANSE
(OP)
I am using Ramsadvance to design a cold formed steel stud wall for shear, axial and lateral loads
What is the correct Material to enter in Ramadvance
MarinoWare catalog says material is A653 33 ksi, but that's not one of the choices, yet the software has cold formed SSMA sections, so one of the listed material choices must be right
Apart from a satisfactory frame analysis with RamAdvance, how are screw connections analyzed. For example, say you want to use a #10 screw. How do you figure how many? Are there charts for this?
Any good (and simple) software for cold formed steel design? I think I am doing this the hard way!

But notice I said I only use the computer to ANALYZE cold formed steel. Marino Ware, or Dietrich, or any other major cold formed steel supplier has tables with section properties and moment capacities for all depths and gauges of studs, as well as tables giving allowable stud heights based on wind load, as well as tables giving allowable axial load based on wind load and stud height. They also publish values for screws, based on diameter and stud gauge, as well as weld capacities.

That said, I do a lot of CFS design as well. I use RISA occasionally to check complex framing and obtain reactions. Otherwise we use a simple program that checks studs per AISI. It is not published any more or I would give you a link.
When checking connections, it is easiest to do those by hand. Some programs may handle this but I haven't run into any. Most manufacturers publish allowable shear and pullout values for their screws. Again, you may also find screw capacity with the AISI code, chapter E. Usually I find that is best since you aren't constrained to any particular brand of screw and you don't have to worry about possible bogus test results. The AISI code will also provide a means for checking block shear, pull-over (different from pull-out) and other failure modes as well as give you the proper LRFD factors or safety factors to use. Be conservative with screw connections. A few more screws won't kill anyone and will help cya when they miss some or strip some holes.
The code will also list common steel materials along with properties. In your program, it is more important that you have the proper yield and tensile strength than the designation of the material. For 43-mil and thinner, use Fy=33ksi and Fu=45ksi. For 54-mil and thicker, use Fy-50ksi and Fu=65ksi. These are most common.
Basically if you are in cold-formed steel design, you need to get the AISI code.
