Cold Formed Steel Design
Cold Formed Steel Design
(OP)
I would like to know how different engineers design:
1. Stud splice (only for lateral/wind load)
2. Base connection design (thicker track or stiffclip if necessary) for cantilever (parapet) studs including the fasteners design (we specify STEEL NETWORK STIFFCLIPS under these circustances, however, I am looking for an alternate to STIFFCLIP connection)
Attached, please find the sketches.
Appreciate your help.

2. For a lightly loaded cantilever, I use a thick track with power driven fasteners. For a more heavily loaded cantilever, I use a StiffClip, or a conventional steel angle with an expansion anchor.

I agree with you on item 1. However, this is an example. I just want to see how you do it (calculations please, if possible).
Also, in item 2, I would like to see how you show design calculations with tracks and PDFs condition.
RE: Cold Formed Steel Design
In a continious cantilever I put a continuous steel plate nested in the track and bolted to the structure.

Anyway, you could place a "red" steel vertical angle or channel every 4-6 ft with a moment connection to whatever your base material is. Then you can just infill your studs normally. The top track spans between vertical posts.

2) You will need to create a fixed base. What we have done in the past is install "kicker" braces every so often (3-4 feet on center). Then use a top track capable of spanning between the braces. This will eliminate the need for fixity at the base.
