Cold Formed Purlin on Truss

Cold Formed Purlin on Truss

(OP)
I am looking at cold formed channel sections to span 5 m on secondary beams lying on trusses.

What design checks do I need to carry out? any guidelines you use?

p.s small loads
Uplift 0.999Kn/m2
Dead loads 0.14kn/m2 (just the standing seam roof system)
Imposed 1Kn/m2

Purlin spacing 1.4m

Thankyou!

RE: Cold Formed Purlin on Truss

Use a standard cold formed section shape and use the section properties and load tables furnished by the manufacturer
