Cold formed steel
Cold formed steel
(OP)
Hello,
I am new for Cold formed steel design field.From previous posts on similar topics in this forum, I find lots of good information.Still have few questions and would appreciate any help:
-the project I am talking about is one story building with CFS framing: what will be the best selection for roof framing: bar joist or Cold Formed Steel truss?.The roof will be monosloped. I don't see Dietrich catalog on truss,who is the commonly used MFR on truss.
-What is the common practice for Header/jamb design: designing a built up section or using HDS or similar assembly from Dietrich.As I see dietrich has pre-fabricated assembly of heavy duty studs for header and jamb.
-is there any reference material that shows a complete design of CFS framing building.I don't have the CFS design manual-does this cover most of itmes and worth bying?
thanks a lot in advance.

Which design standard do you have to use?
Check this list with design examples. Some of them are for the design of basic cold-formed structural elements (beams, columns etc).

I have seen jamb and header shapes by the Steel Network and Dietrich used instead of built-up members. You could probably count on better quality if using the proprietary jamb rather than specifying a built-up section and relying on the installer to connect the members according to your drawings.
The AISI manual and their several other publications have examples. I don't know of one that goes through a complete building example though.
RE: Cold formed steel
At moment I have working in a company that is apllying the construction methode of light steel framing and i need a programe who helps me to make and analyse de structures, make output designs and calculate de forces. Somebody can give me the link for the steel smart system? The steel network site seem's to be always down.
Thanks,

The link for Steel Smart is below, I haven't come accros server down problem- have not used the sofrware yet but seems very impressive:

share your experience in Cold formed design.
thanks
RE: Cold formed steel
I have two more questions to all about little more specific details on CFS framing System:
1) Parapet Detail in CFS framing system. How the parapet detail look likes.The Ht of parapet is 3ft, and my question is do we provide kicker at top of parapet stud or we cantilever parapet stud.
2) As the structure of roof will be sloped requiring varying height of studs which seems little hectic for construction.What's your experience on these? How better is to make roof structure flat and taper the insulation any limits on that.
Your thoughts will be Greatly appreciated.
thanks.

2. Tapered insulation is ok if the maximum insulation thickness is not excessive. Too much and you won't be able to find screws long enough to attach the insulation to the deck, not to mention it increases your loads. CFS framers can deal with varying stud heights without much issue, though they won't like it.
RE: Cold formed steel
Now the remaining option being cantilever parapet .As the wall studs stop below roof and the parapet studs start from there as a two separate members. What is the best connection to make the parapet stud as a cantilever member ?.I am thinking using straps on both flanges and connecting the studs(above and below) to make a moment connection.
Any thoughts/suggestions appreciated.
