Cold Form Steel Truss Splicing ???

Cold Form Steel Truss Splicing ???

Cold Form Steel Truss Splicing ???

(OP)
I am designing a 28 m long cold form steel multi span truss (89 cee profile), which is supported by the 150mm LGS wall, so my question is that, transportation length is limited to 10 m so I want to break my truss into 3 parts so any one can suggest what is the proper way to splice the top and bottom chord @ supported wall location (how I can splice TC and BC @ supported wall)???
Does the truss result will remain same even after splicing or I need to design all three parts of truss individually?

RE: Cold Form Steel Truss Splicing ???

I think the simplest approach would be to design it as three totally separate trusses.

Design it as three independent trusses. Then your only splicing would be for erection ease and continuity of diaphragm chords and collectors.

Thx for your reply...
if i design each truss separately then 75 mm wall bearin for each truss will b enough however span is about 10m but truss is only carrying sheeting and insulation load???
How i can connect the truss with each other for continut??

Why is it that you feel that you need continuity? I like the three separate truss approach as well. If you need continuity, I suppose that you could install sort of a nested track onto the chords once the trusses arrive on site and design the fastenings for the chord forces. One difficulty with that may be getting the terminal webs of the various trusses to meet up concentrically at the splice locations. Your light gauge chords won't be able to handle much shear or bending arising from eccentric nodal connections.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
