Cold Formed Purlin Cleats/Clips
Cold Formed Purlin Cleats/Clips
(OP)
I don't have much experience with cold-formed structures. I was looking at some details from PEB suppliers that shows a clip/cleat welded to a roof beam. The Z purlin is bolted to this clip.
Is rotational restraint at the support provided by the weak axis bending capacity of the clip? How do you calculate what thickness is needed? If you can point me to any literature, that would be great.

It’s no trick to get the answers when you have all the data. The trick is to get the answers when you only have half the data and half that is wrong and you don’t know which half - LORD KELVIN

See Page 9 of the following for sizes of cleats we use in Australia, assuming the purlin is just above the rafter.

Any literature on assessing the forces on the roof? Are we talking about the horizontal component of gravity loads? Won't some of these forces be carried by the anti-sag /roll rods or bridging?
